How to Buy a Used Car Without Surprises
- Get an itemized out-the-door quote in writing before you visit. If a dealer won’t send one, keep shopping.
- Ask what fees apply to used cars. Reconditioning, prep and certification fees often show up only on used vehicles.
- Ask for all dealer add-ons removed. Window tint, nitrogen and protection packages are optional.
- Get the vehicle history report and an independent inspection. A fair price on a car with problems is not a good deal.
- Compare at least three dealers. Used-car doc fees in the same metro can differ by hundreds of dollars.
Rankings are generated from the CarEdge Dealer Transparency Index, a public methodology that scores dealers on verified out-the-door quotes, not Google star ratings or paid placements. CarEdge refreshes the rankings daily as new verified quotes come in.
