Used Car Inspection Checklist Before You Buy

8 min readBy the mechanics at Aaron's Auto Repair

The short answer

Before buying a used car, check the title and VIN history, scan for stored trouble codes, inspect for leaks, flood damage, and uneven tire wear, measure brake life, and take a 15-minute test drive at highway speed. A professional pre-purchase inspection costs far less than one hidden repair.

Paperwork and history

Match the VIN on the dashboard, door jamb, and title. Run a history report for accidents, salvage, or flood branding. In Texas, check that the title is in the seller's name and not marked 'salvage' or 'rebuilt' unless disclosed.

Exterior and body

Look down the sides for wavy panels, mismatched paint, and uneven panel gaps that suggest accident repair. Check under the car for rust and fresh undercoating that might hide damage.

Flood damage warning signs

After heavy North Texas storms, flood cars hit the market. Watch for:

  • Musty or heavy air-freshener smell
  • Silt under seats or in the spare tire well
  • Rust on seat rails and pedal brackets
  • Fogged headlights or gauge cluster
  • Electrical glitches

Under the hood

Check oil for milky residue, coolant for oil contamination, belts for cracks, and look for leaks. Scan the computer — recently cleared codes show as 'not ready' monitors.

The test drive

Drive cold and hot, at city and highway speed. Feel for shifting delays, vibration, pulling, and listen for clunks. Test the AC thoroughly — it's expensive to fix in Texas.
