Pre-Purchase Car Inspection Checklist
A thorough inspection can save you thousands by revealing hidden problems. Use this comprehensive checklist when evaluating any used car. Print it out and bring it with you.
Buying a used car is one of the smartest financial decisions you can make, but only if you buy a reliable vehicle without hidden issues. This pre-purchase inspection checklist covers everything from the exterior body and paint to the engine, transmission, brakes, and interior. Whether you are buying from a private seller or a dealership, taking the time to inspect the vehicle thoroughly can prevent costly surprises down the road. We recommend bringing this checklist with you and taking your time during the inspection.
Important: Always get a professional mechanic inspection ($100-150) before buying!
