Pre-Purchase Car Inspection: How to Find the Right Mechanic
Your Best $150 Investment
A pre-purchase inspection (PPI) by an independent mechanic typically costs $100-$200 and can save you from a $5,000-$15,000 mistake.
Finding the Right Mechanic
Use a mechanic with no relationship to the seller. Ask friends for recommendations, check Google Maps reviews, and look for ASE-certified mechanics. Never use the dealer's own service department.
What to Tell the Mechanic
- Tell them you're considering buying this vehicle and want a complete inspection.
- Ask them to check the frame for damage or prior repairs.
- Request a compression test if the car has over 100,000 miles.
- Ask them to scan for all stored diagnostic codes — even inactive ones.
- Ask for a written report with specific findings and estimated repair costs.
What If the Seller Refuses?
Walk away immediately. A seller who refuses an independent inspection almost certainly has something to hide.
Using the Report as Leverage
A PPI that reveals necessary repairs is a negotiating tool. Present it and ask for a price reduction equal to the repair cost.
