The Pre-Purchase Inspection Checklist We Actually Use

A good pre-purchase inspection is not a mechanic glancing at a car. It is a structured process, and you can direct it even if someone else is holding the torch.

Cold start

Insist the engine is cold when you arrive. Listen for chain rattle, VANOS noise and lifter tick in the first thirty seconds. A warm engine on arrival is a red flag by itself.

On the lift

Check the subframe mounting points, differential mounts, oil pan gasket, power steering lines, control arm bushings and the exhaust hangers. Photograph everything.

Paint and panels

A depth gauge takes ten minutes and settles most arguments. Consistent readings across the car indicate original paint; a panel reading double the rest indicates filler.

Electronics

Cycle every window, the sunroof, the convertible top, the climate control and every seat adjustment. On older cars, check the instrument cluster pixels.

Scan the modules

A full fault-code scan across all modules, not just the engine. Cleared codes reappear. Ask when the codes were last cleared.
