What is a pre-purchase inspection?
A pre-purchase inspection (PPI) is a mechanical check performed by an independent mechanic on a used vehicle before you buy it. The mechanic examines the engine, transmission, brakes, suspension, electrical systems, and body to identify existing or potential issues. You get a full report before committing to the purchase.
Why you need one before buying a used car
A car that looks clean and drives fine on a short test drive can have significant hidden problems. An independent mechanic inspection reveals issues the seller may not disclose — or may not even know about. It's the single best way to avoid buying a problem vehicle.
How it works on Informal Auto
Browse inspection listings, book an inspector in the area where the car is located, and arrange for the mechanic to meet you at the seller's location. The mechanic performs the inspection and provides a report. You decide whether to proceed with the purchase.
What a PPI covers
Engine condition and leaks, transmission and drivetrain, brakes and rotors, suspension and steering, tires, electrical systems, AC and heat, frame and body condition, fluid levels and condition, and a road test.
