What Does a Pre-Purchase Inspection Check on a Used Car?

May 30, 2026 5 min readBy Playa Vista Automotive

A pre-purchase inspection checks the engine, transmission, brakes, suspension, tires, fluids, electronics, stored trouble codes and signs of accident or flood damage before you buy.

What is a pre-purchase inspection?

A pre-purchase inspection (PPI) is an independent mechanic's check of a used car's condition before you buy it. It identifies existing problems and upcoming repairs so you can negotiate or walk away.

What does a pre-purchase inspection include?

Our inspection covers: - Engine: leaks, noises, belts, hoses, mounts - Transmission: shift quality, fluid condition - Brakes: pad and rotor wear, fluid - Suspension and steering: shocks, struts, bushings, alignment wear - Tires: tread depth, age, uneven wear - Electrical: battery, charging system, lights, accessories - Computer scan: stored and pending trouble codes, readiness monitors - Body and frame: accident repair, rust, flood damage signs - Road test

Why check readiness monitors on a used car?

Unset readiness monitors can mean the battery was disconnected or codes were cleared recently to hide a problem. California smog checks also require these monitors to be set.

Is a vehicle history report enough?

No. A history report lists reported events; it cannot show current mechanical condition or unreported accident repairs. Use both.

When should I schedule the inspection?

Schedule it after you have agreed on a price in principle but before you pay or sign. Make the sale conditional on the inspection.
