## The short version

- Depreciation is not a fee. It is the distance between two prices — the one you agree on the way in, and the one somebody else agrees on the way out. Until that second price is agreed, the loss is only on paper.
- It is usually the largest single figure in the cost of running a car, and the only one you never hand over. It is deducted from you at the end, by whoever takes the car next.
- The curve is front-loaded: quick at the beginning, slow later. That asymmetry is the whole structural case for buying used, and it is not a claim anybody has to sell you.
- Two different things are folded into every depreciation figure — the car ageing, and the market for cars like it moving. Nearly everything written on the subject quietly assumes the second one is zero.
- It is not zero. The federal used-vehicle price index stood at 137.5 in January 2005 and 136.915 in June 2020, barely moved in between, and then added 45.24% in a single year.
- Nobody can tell you what percentage your car will lose, and that includes us. What can be set out honestly is what decides it, and which parts of it are yours.

Everybody has heard the sentence about driving off the lot. Most people also remember a percentage attached to it. The interesting thing about those percentages is that no two of them agree, hardly any of them arrives with a source, and every one of them describes a market that has already been replaced by the time it reaches you.

This page will not hand you a better number, and it is worth saying so at the top rather than burying it at the bottom. Depreciation is not a property of a car in the way that its weight or its fuel consumption is. It is the gap between two prices set by two different markets at two different moments, and only the first of those moments has happened. What can be shown, rather than asserted, is the second half of the problem: how the market for used vehicles has actually behaved. We hold the federal index that measures it, monthly, back to 2005.

**Figure: The used vehicle price index, year by year**

Line chart of the Bureau of Labor Statistics used cars and trucks price index annually from 2005 to 2026, flat for roughly fifteen years before rising steeply into 2022.

Fifteen years of a market that barely moved, then two that undid the assumption underneath every depreciation table written before them. The monthly series bottoms at 121.061 in 2009 and peaks at 213.683 in 2022; the steepest year-on-year move is 45.24 per cent, in June 2021. Read what this is carefully: the CPI holds a constant basket of vehicles, so it measures the market moving, not any individual car ageing. Depreciation is those two effects together, and most writing on the subject quietly assumes this one is zero. Points are annual means; the last is a part year. Source: BLS series CUUR0000SETA02.

That is 259 consecutive monthly readings of the used cars and trucks component of the US Consumer Price Index, averaged across American cities and published every month by the Bureau of Labor Statistics. Read it as a picture of a market rather than a picture of a car. For fifteen years it does very little. Then it does something that had no precedent in the record, and the shape of that episode is the reason this page exists.

**What this index is, and what it is not.** The CPI is a price index, not a transaction price and not a depreciation curve. What it prices, month after month, is a basket of used vehicles deliberately held constant — the contents are pinned in place so that the only thing left free to move is the price. That makes it a measurement of the *market*, not of any individual car getting older. It cannot tell you what your car is worth, it is not a valuation, and no figure on this page should be read as a rate at which a vehicle loses value. What it can do is settle a question most depreciation writing never even asks: whether the ground under the whole exercise stays still.

## Depreciation is a subtraction, not a payment

Start with the definition, because a surprising amount of the confusion around this subject is grammatical rather than financial.

Depreciation is what you get when you take the price you paid for a car and subtract the price you are eventually paid for it. That is the entire quantity. It has two inputs, both of them prices, both of them agreed between two consenting parties on a particular day. Neither of them is a property of the vehicle. A car sitting in a garage has no value in the sense that matters here; it acquires one at the moment somebody offers.

Two consequences follow immediately, and both of them are routinely got wrong.

**Depreciation is not something you pay monthly.** Nothing leaves your account. There is no schedule, no statement, no direct debit. Accountants amortise a vehicle across its useful life because a business needs to spread the cost over the periods that benefited from it, and that convention has leaked into consumer writing in a way that does real damage. You are not a business, and the number you would write down at the end of year two is a bookkeeping estimate, not a transaction. Until the car changes hands, the loss is on paper.

**It is realised only once, at the exit.** The car you keep for fifteen years and then scrap has depreciated by the whole of what you paid, spread across fifteen years of use. The car you keep for eighteen months and sell has depreciated by whatever the market decides in that specific week of that specific year. Same vehicle, wildly different outcomes, and the difference is entirely a matter of when you chose to convert it back into money.

That is not a technicality. It is the reason the single most effective thing anyone can do about depreciation is also the least discussed: keep the car longer. Not because the car loses less — it loses more in absolute terms the longer you hold it — but because the front-loaded part of the loss gets divided across more years of use. The person who changes cars every three years pays the expensive part of the curve repeatedly. The person who keeps one for a decade pays it once.

## The largest cost you never actually hand over

For most owners, over most holding periods, depreciation is bigger than fuel, bigger than insurance, bigger than servicing and repairs. It is also the only one that is invisible in a bank statement, and the mechanism of that invisibility is worth spelling out because it is not simply that people forget.

Every other cost of running a car is *paid*. You initiate it. Money moves from you to somebody else, on a date, in an amount you can see. Depreciation is *deducted*. It accumulates silently while nothing happens, and it is settled at the end by the person buying the car from you, in the form of an offer that is lower than the number in your head. Nothing is ever handed over. Somebody else simply declines to offer as much as you had in mind.

That structural difference is why the cost so often arrives feeling like an injustice rather than like an expense. The dealer offering less than you hoped is not taking anything from you; they are showing you the bill for something you have been consuming for years. It reads as a bad negotiation because it is delivered by a negotiator.

How to build this into a budget before it happens is a separate question, and one our guide to [what you can actually afford to spend on a car](https://baronauto1.com/financing/how-much-car-can-i-afford/) works through in detail. The point to carry out of this section is narrower: any calculation of what a car costs you that starts from the monthly payment has already omitted the largest term, because the largest term never appears as a payment.

## Why the early years are the expensive ones

Almost every model follows the same broad shape. Value falls quickly at first, then more gently, then very gently indeed, until the car reaches a floor set by what it is worth as transport and parts rather than as a desirable object. Nothing about that is controversial. What is worth understanding is why the front of the curve is so much steeper than the rest, because the reasons are separable and they behave differently.

### Newness is a feature, and it can only be sold once

A substantial part of what a new-car buyer pays for is not mechanical. It is the state of being first: the untouched interior, the unwritten history, the delivery, the plate, the fact that nobody else has ever owned it. That is a genuine product and people pay real money for it. But it is consumed entirely by the first transaction. The moment a car has one owner, it can never again be a car with none, and the whole of that premium is gone in a single step that has nothing to do with wear.

### The information problem arrives at the same moment

A new car carries a manufacturer’s guarantee about what it is. A used one carries a claim by whoever is selling it. The second buyer has to price the possibility that something is wrong that they cannot see — a neglected service interval, a repaired collision, a history that does not match the paperwork. That uncertainty discount is applied once, at the first change of hands, and it is real even when the car is perfect, because the buyer cannot know that it is.

### Warranty coverage is being spent

The remaining factory warranty is an asset with a running-down clock, and it is worth most when it is longest. As it depletes, the buyer is taking on more of the repair risk, and the price adjusts for it. This runs out on a schedule, which is why it produces a fairly predictable decline early and then stops contributing at all.

### Then the fall slows, because the reasons for it are used up

Once the newness premium is spent, the information discount applied and the warranty gone, what remains is a car being valued as a car. From that point the decline is driven mostly by accumulating mileage, ordinary wear, and the slow drift of the model out of fashion. Those are gradual and roughly linear, which is why the back half of the curve is close to a slope rather than a cliff.

The used buyer is standing at the point where the expensive reasons have already been paid for by somebody else. That is the whole argument, and it is not a persuasive argument so much as an arithmetic one. Everything in the next section is a variation on it.

## What actually moves the second price

The temptation is to treat depreciation as something the car does. It is more accurate to treat it as something other people do to the car, in the form of how many of them want one and what they will pay. Here is what that resolves into, ordered roughly by how much it matters.

**The inputs to a resale price, what each one does, and when it is decided. Nothing in this table is quantified, deliberately: the size of each term varies by model, region and year, and any figure printed here would be an average of things that are not alike.**

| Input | What it does | Whose decision it is |
| --- | --- | --- |
| Demand for that specific model | The dominant term. A car people actively look for second-hand resells near its cost. One nobody searches for is discounted regardless of its condition. | Yours, entirely, and only once — at purchase |
| Mileage | Continuous and cumulative. It is also the one input you add to every single day you own the car. | Shared: partly your driving, partly the car you chose |
| Condition and documentation | Two separate things sold as one. Physical condition is what a buyer sees; documentation is what lets them believe it. Recorded servicing is worth more than remembered servicing. | Yours, throughout ownership |
| Title status | Not a discount but a reclassification. A salvage, rebuilt or flood brand permanently changes what the car is to insurers, lenders and buyers, and it does not fade with time. | Nobody’s — but it is checkable before you buy |
| Fuel type and body style | Revalued by fuel prices, tax treatment and policy rather than by anything under the bonnet. The car does not change; the category it sits in does. | Yours at purchase, then out of your hands |
| Brand reputation | Slow-moving and largely accurate, but already reflected in what you paid. You buy the reputation and you sell it again; the profit on it was taken by the manufacturer. | Yours at purchase |
| Colour and specification | Real but marginal, and it bites hardest at the extremes. Unusual colours and rare option combinations narrow the pool of interested buyers, which matters more on a slow sale than on an average one. | Yours at purchase |
| The market itself | Can exceed all of the above combined. It is the term this page is really about, and the only one nobody involved in the transaction controls. | Nobody’s |

Two rows in that table deserve more than a line each.

**Title status is the only one that is binary.** Everything else on the list is a matter of degree; a brand is a step change. A car that has been written off and rebuilt is not a slightly cheaper version of the same car, it is a different asset with a different set of buyers, a narrower financing market and a permanently lower ceiling. Our page on [what a branded title actually means](https://baronauto1.com/vehicle-history/what-is-a-branded-title/) sets out each brand and what each one does. The relevant point here is that the markdown is inherited: whoever owns the car when the brand is applied takes the hit, and every owner afterwards buys and sells inside the reduced range. It is also the one item on the list that can be settled before you commit rather than discovered afterwards: you can [check the title brand against the VIN](https://carcheckervin.com) in less time than the test drive takes, which makes skipping it an unusually expensive omission.

**Mileage is the only one you add to continuously.** It is worth pinning down what mileage actually does, though, because the market prices it far more crudely than the engineering justifies. Buyers respond to round numbers, so an odometer that has just ticked past a significant-looking figure knocks money off a vehicle that is mechanically indistinguishable from what it was the week before. We looked at where failures are actually reported in [how many miles is too many](https://baronauto1.com/buying-guides/how-many-miles-is-too-many/), and the short version is that the cliff buyers price for is not present in the failure data. That gap between what the market believes and what the record shows is where a patient buyer finds room.

## The two things inside every depreciation figure

Here is the part that most writing on this subject leaves out, and it is not a small omission.

When you sell a car for less than you paid, two entirely separate processes have contributed to that difference. The first is that the car got older, accumulated miles, used up its warranty and moved down the curve described above. Call that the ageing effect. The second is that the market for used vehicles as a whole may have moved between the day you bought and the day you sold. Call that the market effect. The number you experience is the two of them added together, and you cannot see which is which from the inside.

Almost every depreciation figure in circulation — the residual-value tables, the retained-value awards, the rules of thumb, the confident percentages — is a statement about the ageing effect that has silently set the market effect to zero. That assumption is never stated, because it is never noticed. And it is a perfectly reasonable assumption right up until the moment it is not.

The federal index is useful precisely because it isolates the term that gets ignored. By holding the basket of vehicles constant it deliberately strips out ageing: the thing being priced each month is a comparable set of used cars, not the same physical cars getting older. Whatever moves is therefore the market and nothing else. That is the reason it can answer a question no depreciation schedule can, which is whether the ground itself is level.

**The sentence to carry away.** A depreciation forecast is a claim about a car *and* a claim that the market will not move. The first is usually reasonable. The second is never stated, never tested, and was catastrophically wrong within the last few years.

## The years the curve ran backwards

For most of the span in the chart above, ignoring the market effect was defensible. The index opened at 137.5 in January 2005. In June 2020 it stood at 136.915. Fifteen years, a financial crisis, a pandemic and a wholesale change in what carmakers were building, and in the index’s own terms the used-vehicle market ended up roughly where it started. It was not motionless in between. The floor of the entire record, 121.061, was printed in March 2009 while the credit crisis was still working through. But across those fifteen years it went nowhere in particular, and nowhere it did not come back from.

An entire generation of received wisdom about depreciation was formed inside that flat stretch. If the market does not move, then depreciation really is just ageing, and a schedule really is a schedule. The rules of thumb worked because the thing they ignored was, for fifteen years, close enough to nothing.

Then it moved. From 136.915 in June 2020, the index reached 198.855 twelve months later — 45.24% added in a year, and nothing else in the record comes close to it. The high-water mark, 213.683, did not arrive until July 2022. Whatever you believe about the causes, and there is no shortage of candidates, the measurement is not in dispute: the level of the used-car market rose by close to half in twelve months and stayed elevated for years afterwards.

Now put that beside the ageing effect. For a car whose ordinary decline over that same year was smaller than the market’s rise — which, given the size of the move, describes a great many cars — the two terms did not merely offset. They crossed. The car got a year older and the price went up. People who had bought a used car in 2019 or 2020 found that the standard advice about their car being an asset in permanent decline had stopped describing reality, and stayed wrong for long enough to matter.

This is not a curiosity. It is the clearest available demonstration that the textbook curve is a description of a tendency under stable conditions, not a law the vehicle obeys. A depreciation schedule that had been applied to a 2019 purchase would not have been slightly out. It would have had the sign wrong.

### What it actually teaches

Three things, in descending order of confidence.

**The market term is not zero and cannot be assumed away.** This is the durable lesson, and it survives whatever you think about the specific causes of that episode. Any forecast of what a car will be worth in four years is also, implicitly, a forecast of what the used market will be doing in four years. That second forecast is the harder one and almost nobody makes it explicitly.

**Which market you buy in can matter more than which car you buy.** Two buyers making identical decisions about identical cars, separated by eighteen months, ended up in materially different positions in that period. Neither was better informed than the other. The variable that separated them was not available to either of them at the time.

**Every body of advice is dated by the regime it was written in.** Anything produced during the surge inherited the surge’s assumptions without announcing them. So did everything produced during the fifteen quiet years before it, and that is the less obvious half of the point: a calm market is a regime too, and writing formed inside one is exactly as parochial as writing formed inside a shock. It is only fair to hold this page to the same test. The index has settled a good deal since the peak, reading 184.661 in the most recent month of our pull, and we have no better idea than anybody else what it does next.

If you want the shorter-horizon version of the same data — how the index behaves inside an ordinary year rather than across two decades — that is a separate question with its own answer, worked through in our piece on [when in the year used cars are actually cheapest](https://baronauto1.com/buying-guides/best-time-to-buy-a-used-car/). The two effects are independent, and the annual one is much the smaller of them.

## “Holds its value well” is a claim about the past

The phrase is everywhere, and it is not dishonest. It is just tensed wrong.

Every retained-value ranking is built by observing what happened to earlier examples of a model in earlier market conditions. That is the only way such a thing could be built — the future has not filed its returns yet. So the claim being made is that a car currently on sale will behave the way its predecessors behaved, in a market that will resemble the one those predecessors sold into. Both halves of that can fail, and they fail differently.

The first half fails when a model changes. A new generation, a different engine range, a shift in where it is built or who is buying it, and the reputation is being extended to a car that did not earn it. Reputations are stickier than products.

The second half fails whenever the market moves, which brings us back to the previous section. During the surge, essentially everything held its value well. That was not a verdict on any particular model, and reading it as one produced a lot of confident nonsense about which cars were suddenly good investments.

There is also a quieter problem with the phrase, which is that strong resale value is already in the price. If everybody knows a model holds its value, that knowledge is priced into what you pay for it. You buy the reputation at retail and you sell it at retail. What you keep is the difference, and the difference is smaller than the reputation suggests, because the market has had years to work it out. The unloved model is cheaper going in for exactly the reason it will be cheaper coming out. Neither is a free lunch, and treating either as one is a mistake.

Fuel type is where this goes wrong most visibly. A drivetrain can be revalued by tax policy, emissions rules, fuel prices or city access restrictions, none of which are mechanical facts and none of which are forecastable from a residual table. A car can be exactly as good as it was on the day you bought it and be worth considerably less because the category it belongs to has been reclassified around it.

## Why buying used is buying the shallow end

Put the pieces together and the case for buying used stops being a matter of thrift and becomes structural.

The expensive part of the curve is expensive for reasons that are consumed once: the newness premium, the first information discount, the early warranty burn. A second owner buys after all of those have been spent and paid for by somebody else. From that point the decline is shallower, and the money at risk is smaller in absolute terms because the starting number is smaller.

The lending figures add something the curve on its own does not, which is that the used market carries a price level of its own and that level moves. The Federal Reserve publishes the average amount financed on used car loans: $16,670.42 ten years ago against $24,897.75 at the most recent reading. Whatever a used car is, it is not a fixed distance below a new one, and the base from which any depreciation percentage would be calculated has been shifting the entire time. Over the same decade the advertised 48-month car loan rate went from 4.17% to 7.47%. Read that rate as a floor rather than as a quote — it is a commercial-bank average on new-car lending, so a used or private-party rate sits above it — but the direction is not in doubt, and it means the cost of carrying a car through the expensive part of its life has risen alongside the balances.

None of which makes a used car automatically the cheaper proposition, and the honest version of the argument has to include what you give up. Buying past the front of the curve usually means buying past the warranty as well. The money a new-car buyer spends on depreciation, a used buyer partly spends on the risk of repairs, and a used-car budget with no reserve in it has not really accounted for the exchange it just made. A [certified pre-owned car](https://baronauto1.com/buying-guides/certified-pre-owned/) is one attempt at buying the flatter part of the curve while keeping some of the coverage, at a price; whether that price is worth it depends entirely on who is standing behind the certificate, which is a different investigation.

There is one more consequence, and it belongs to anybody borrowing. Amortisation is back-loaded and depreciation is front-loaded. Two schedules running in opposite directions guarantee a stretch somewhere in the middle of the term where the payoff exceeds the value, and it is the shape of the curve that decides how long that stretch lasts. That widening gap is what [being upside down on a car loan](https://baronauto1.com/financing/negative-equity-car-loan/) consists of, and it is the one point at which depreciation stops being an abstraction and acquires a date — because if the vehicle is stolen, written off, or has to go when circumstances change, the shortfall falls due immediately.

## Depreciation and reliability pull against each other

Two rules that both sound obviously correct are usually handed out together here. They point in opposite directions, and almost nobody says so.

The rules are: buy the car that holds its value, and buy the car that will not break. They sound complementary. A reputation for lasting is largely what produces strong second-hand demand in the first place, so the same models tend to appear on both lists. And yet at the moment of purchase they conflict, for a reason worth working through carefully.

Strong resale value means you pay a premium going in and recover it going out. That is a good trade if you sell. If you keep the car until it is finished, you paid the premium and there is nothing left to recover, because you have consumed the asset yourself. The buyer who plans to run a car into the ground and the buyer who plans to change in four years are not looking for the same thing at all, and most writing on the subject addresses them as though they were.

Meanwhile a fast-depreciating car is, on its face, a bargain: somebody else has absorbed a large loss and you are collecting the benefit. Whether it is actually a bargain turns on *why* it depreciated, and there are two very different answers.

If it fell because demand is thin — an unloved badge, an awkward body style, a model that never caught on — then the discount is real and it costs you nothing to accept. You will pay it forward when you sell, so it is a transfer between owners rather than a loss of value, and if you keep the car a long time it is close to free money.

If it fell because the car is expensive to keep on the road — poor durability, punishing parts prices, a specialist labour market — then the discount is the market pricing in a cost you are about to incur. You get the money at the front and spend it over the following years, usually with interest and always at inconvenient times.

A depreciation table cannot tell those two cases apart. It records the size of the discount and is completely silent on the cause, which is why using retained-value data as a proxy for reliability is a category error. The two questions have to be answered separately: what does the market think of this model, and what does the record say about this individual car? The first is about a badge. The second is about a VIN, and it is answerable — the title history, the odometer record and the open recalls are all checkable before you spend an afternoon on the car, and a [full history pull on the VIN](https://carcheckervin.com) answers all three before you have committed to anything.

The uncomfortable conclusion is that there is no single car that optimises both. There is a car that suits a short holding period and a car that suits a long one, and the first decision is which of those you are.

## What is actually within your control

Most of what determines depreciation is settled before you own the car, and a fair amount of it is settled by people you will never meet. Here is what is left, in rough order of how much it is worth.

- **Decide your holding period before you decide the car.** This is the largest lever on the list and it costs nothing. The front of the curve is expensive; the further past it you buy and the longer you stay, the less of it you pay per year of use. Somebody who buys at three years old and keeps the car to ten has arranged their finances around the shallow part of the curve almost by accident.
- **Check the title before anything else.** A brand is permanent, it is invisible in the metal, and it is the one item on the list that can be ruled out for free. Everything else you might discover about a car is a matter of degree; this one changes what the car is.
- **Keep the paperwork, from day one.** Documented maintenance is the cheapest thing you can do for a future sale price, and it is worth substantially more than the same work done and not recorded. Receipts, dates, mileages. A folder is a resale asset.
- **Buy the specification you want, not the one you think resells.** Optional equipment is bought at retail and recovered at a fraction. Second-guessing a future buyer’s taste is a bad bet against a market you cannot see; you are far more likely to be right about your own preferences than about theirs.
- **Do not roll a shortfall forward.** Financing a deficit from one car into the loan on the next puts you underwater at the start of a longer term on a vehicle that has its own curve to descend. It is the one move that reliably converts a paper loss into a permanent one.
- **Separate the sale from the purchase when you can.** A trade-in and a purchase settled as a single figure make it impossible to see which side of the deal moved. Two numbers you can check beat one number you cannot.
- **Do not try to time the market.** The chart at the top of this page is the argument against it. If the level of the used market were predictable, the people who trade it professionally would not have been so comprehensively surprised in 2021.

And one thing that is not on the list, because it is not a lever: worrying about it. Depreciation is a cost of use, in the same way that petrol is. A car that has lost value while carrying you to work for six years has not failed at anything. It has been spent, which is what it was for.

## A car is not an investment

It is worth saying plainly, because the language of the previous sections can drift in that direction and the drift is not harmless.

An investment is something you buy in the expectation that it will produce a return. A car is a durable good that you buy in order to use it, and it is consumed in the using. The overwhelming majority of them are worth less every year for the entirely mundane reason that they are wearing out. The handful that appreciate are collectible objects that happen to have wheels, and they are subject to a different market with different rules, most of which have very little to do with transport.

The reason this matters is not pedantry. Treating a car as an investment produces a specific and expensive class of mistake: paying more up front to protect a resale value that is uncertain, illiquid and years away, in preference to buying the car that suits what you actually need to do. Depreciation is worth understanding so that you are not surprised by it and not misled about it. It is not worth optimising a purchase around, because the thing you are optimising is a forecast of other people’s preferences in several years’ time, and this page has spent several thousand words explaining why that forecast is weaker than it looks.

Nothing on this page recommends any particular car or any particular decision. It describes how the number works, so that the choice you make is made with the mechanism in view rather than behind a curtain.

Depreciation is also the hidden term in the lease-or-buy question, since a lease is largely a way of paying for it directly. Our guide to [lease versus buy](https://baronauto1.com/financing/lease-vs-buy-car/) sets both against the third option that comparison usually leaves out.

## Common questions

### What is car depreciation, in one sentence?

It is the difference between the price you paid for a vehicle and the price you receive when you dispose of it. Everything else — curves, schedules, percentages — is an attempt to estimate that difference before the second price exists.

### How much value does a car lose in the first year?

There is no honest single answer, which is why you will not find a figure here. The loss depends on the model, the mileage, the condition, the specification and, critically, on what the whole used market does during that year. The federal index added 45.24% in a single twelve-month stretch of this series, and went essentially nowhere across the fifteen years before it. Any first-year percentage you are quoted is an average taken over conditions that may not be the conditions you are in.

### Do I pay depreciation while I own the car?

No money leaves your account for it. The loss accumulates on paper and is realised in a single event when you sell, trade or scrap the vehicle. That is why it is so easy to leave out of a budget and so unpleasant when it finally lands.

### Can a used car go up in value?

Yes, and not only in the collectible sense. Depreciation combines the car ageing with the market moving, and when the market moves upward faster than the car ages, the resale price can exceed the purchase price. It happened on a national scale between 2020 and 2022, when the federal index climbed from 136.915 to a peak of 213.683 and then stayed high for years. It is unusual, it was not predicted, and it is the clearest evidence that the curve is a tendency rather than a rule.

### Does high mileage always mean a car has depreciated more?

Mileage is one of the larger inputs, but it is not the only one and the market prices it more crudely than the engineering justifies. A high-mileage car with a complete service record and a clean title can be worth more than a low-mileage one with an incomplete history or a title brand. Age, condition, documentation and demand all move the number too.

### Which colours and options hold value best?

Conventional colours and mainstream specifications have a wider pool of potential buyers, which mostly shows up as a faster sale rather than a much higher price. The effect is real and it is small — it sits near the bottom of the list of things that determine a resale price, well below demand for the model, condition and history. Choosing a car you do not want in order to please a hypothetical future buyer is usually a poor trade.

### Does the price index on this page tell me what my car will be worth?

No, and it is important that it does not get read that way. The CPI holds a constant basket of used vehicles and measures what that basket costs from month to month, so it describes the market rather than any individual vehicle ageing. It is the right instrument for the question “has the used-car market moved?” and the wrong one for “what is this car worth?” Nothing on this page is a valuation.
