Used-⁠car checks and scams

How to catch title, odometer, and flood problems before you pay.

Fees, add-⁠ons, and the deal

Know which charges are set by law, which are the dealer's, and which you can say no to.

Money and paperwork after you sign

Return a car, get refunds, and fix problems with what you bought.

Guides by type of deal

Step-by-step plans for each way to get a car. You might need more than one, like a used car with a loan.

Understand what the dealer is doing

Start with what is happening now. Go deeper if you need to.

Check the numbers

Use the numbers from your written offers.

Check the car itself

A VIN check, a recall lookup, and a mechanic's inspection each catch different problems.

Before and after you sign

Keep your final terms, papers, and deadlines in one place.

Official sources

These government pages are free. Some history-report sellers charge a fee, and no report replaces an independent inspection.

Check important details against these sources and your own paperwork. See how we check our advice, or what the tools save in your browser.
