inspecting car tire wheel bearings joints brakes mechanic

A couple years ago, my wife and I were searching for a car to purchase for her, after her last set of wheels decided to retire early. Intent on finding a used car in good quality and at a decent price, we went on a scavenger hunt inspecting used cars at local dealerships and private sellers around town.

In the process, we developed this exhaustive list of items to check on each used car we considered. Hopefully sharing our checklist with you will help you in your search for your next car. We still recommend taking into a mechanic you trust before buying it, but hopefully this will give you an idea of if the car’s worth your time.
