# Baron Auto > Independent, research-backed guides to buying, financing, and maintaining used cars — grounded in NHTSA and EPA data. This site is under new ownership and is not affiliated with Baron Auto Emporium dealership. This site sells nothing, holds no inventory and takes no advertising. It is independent reference material about buying, checking and maintaining used cars in the United States. Every factual figure on this site traces to a named federal source — NHTSA recall, complaint and safety-rating records, and EPA fuel-economy data — and each article lists the databases it drew on. Retrieval dates are printed on the page, because federal data changes. Each URL below is the markdown alternate. Drop `index.md` for the HTML page. ## Guides - [Used Car Maintenance Tips: The Schedule That Actually Matters](https://baronauto1.com/car-care/car-maintenance-tips/index.md): A maintenance schedule written for cars past their warranty: which intervals protect the engine, which dealer services are padding, and what owner complaint data says fails first. - [How to Protect Your Car From Rust](https://baronauto1.com/car-care/how-to-protect-your-car-from-rust/index.md): Road salt kills cars from underneath.
