Used car guides built on federal data, not sales copy
Baron Auto is an independent resource for people buying used cars. Every guide here starts from public records — NHTSA recall campaigns, owner complaints filed against specific model years, EPA fuel economy figures — and explains what they mean when you are standing on a lot deciding whether to hand over money. We do not sell cars, loans, or insurance.
Before you buy
The repair does not show on the paint. It shows in the record.
Check any VIN
Decode the year, model, trim, plant and engine, then check NMVTIS for title brands and NHTSA for open recalls.

Tire Rotation Cost, and What Skipping It Actually Costs

Why trust this site
We publish the source behind every number. Recall counts, complaint totals and fuel-economy figures come from NHTSA and the EPA and are dated on the page, so you can re-run any of them yourself. Where an article recommends a check, it links to the free federal tool that performs it. Where we think a paid service is worth it, we say why — and where it is not, we say that too.
