Overview
Summary and key details for this checklist.
Performing a thorough inspection is the most effective way to avoid "buyer's remorse" when purchasing a used vehicle. This process typically takes between 60 to 90 minutes for a DIY enthusiast, though a professional Pre-Purchase Inspection (PPI) at a shop may take 2 hours and provide a more technical diagnostic report.
Our checklist is divided into logical phases: the static exterior walk-around, the interior functional test, the under-hood mechanical review, and the dynamic test drive. Completing these steps helps you negotiate a fair price or walk away from a bad deal.

Use the table above as your primary guide during the physical walkthrough. Mark each item as you go, and don't be afraid to ask the seller for clarification on any failures found.
If you find more than three 'Required' items failing, it is often a sign of poor maintenance. Use these findings as leverage for price negotiation or as a reason to seek a professional mechanic's opinion.
Notes
Extra context, cautions, and helpful tips.
Once the inspection is complete, take a moment away from the seller to review your notes and decide if the vehicle meets your safety and budget requirements.
- Keep a digital copy of your inspection notes for future reference.
- Always verify the VIN on the vehicle matches the VIN on the insurance and title.
- If maintenance records are missing, assume the 30k/60k/90k services are due.
- Check for open recalls using the NHTSA website.
- Don't forget to check the spare tire and jack kit.
- Test all keys and fobs; replacements are expensive.
- Verify the heater works even in summer, and AC works in winter.
- Reset your expectations: no used car is perfect, but it should be safe.
- Browse our Tire Inspection or Fluid Guide for deeper dives.
