Used car inspection FAQ
What should I check when buying a used car?
Check the title and vehicle history, the exterior for rust and mismatched paint, fluids and leaks under the hood, interior electronics and flood signs, and how the car drives. Finish with an independent mechanic inspection.
How much does a pre-purchase inspection cost?
An independent pre-purchase inspection usually costs $100 to $250. It often finds problems worth far more than that and gives you leverage to negotiate.
How can I tell if a used car was in a flood?
Look for a musty smell, damp or new carpet, silt under the seats or in the trunk, rust on seat rails and screws, and fogged lights. A vehicle history report can show a flood title brand.
How do I check for odometer rollback?
Compare the odometer to mileage on service records and the vehicle history report, and look for wear on the pedals, steering wheel and driver seat that seems too heavy for the miles shown.
Can a dealer refuse a pre-purchase inspection?
They can, but that is a major red flag. A trustworthy seller lets you take the car to your own mechanic. If they refuse, consider walking away.
