Sales tax on a used car depends on who sold it, where you register it, and whether you traded something in. Here's how dealer vs private-party tax works, which states shrink the trade-in credit, what no-sales-tax states still charge, and how Texas, Virginia, Delaware, and North Carolina check a lowball bill of sale.
A repaired car still loses resale value once the accident shows up on its history report. Here's how diminished value claims work, how the 17c formula lowballs them, which states allow them, and how to build a claim with real evidence.
GAP can cover what you still owe if a financed used car is totaled, but insurers often won't sell it on older cars and dealer prices run $500 to $700. Here's when it's worth it, what the CFPB and state law say, and how to get a refund.
A pre-purchase inspection usually runs $150 to $300 at an independent shop. Here's what Consumer Reports, RepairPal, and the FTC say it should cover, why a dealer's own inspection isn't enough, and how to set one up.

Yo-yo financing happens when a dealer lets you drive off before the loan is final, then calls you back to sign worse terms. Here's how spot delivery works, what the CFPB, FTC, California and Illinois law say about your down payment and trade-in, the 2026 Anaheim arrest case, and what to do if the dealer calls.
A dealer doc fee is the dealer's own paperwork charge, not a tax or DMV fee. State caps range from $85 in California to $800 in Maryland, and Florida has none.

There's no federal three-day return on a used car, and the FTC Cooling-Off Rule excludes vehicles.
