The short answer
Before buying a used car, check the vehicle history report, scan for stored and pending trouble codes, inspect for leaks, frame or flood damage, test brakes and suspension, and take a 15-minute test drive. A professional pre-purchase inspection ($129–$199) catches what you'll miss.
Paperwork and history
Verify the VIN matches the title and check Carfax or AutoCheck for accidents, title brands and service records.
Under the hood and underneath
Look for oil and coolant leaks, rusted brake lines, frame repairs and silt in crevices (flood sign).
The test drive
Test cold start, shifting, braking, steering and listen for noises at highway speed.
