What is a pre-purchase inspection?
A pre-purchase inspection is a comprehensive mechanical check performed by an independent mechanic on a used vehicle before you buy it. The mechanic examines the car from bumper to bumper and provides a report of its condition, including any existing problems, potential issues, and estimated repair costs if applicable.
What a PPI covers
Engine condition and any leaks, transmission and drivetrain, brakes and rotors, suspension and steering, tires, battery and charging system, AC and heat, electrical systems, fluid levels and condition, body and frame for signs of accident damage or rust, and a road test to check for unusual noises or behavior while driving.
Why you need one
A used car that looks clean, starts fine, and drives okay on a short test drive can still have significant hidden problems. Oil leaks, worn suspension components, transmission issues, and frame damage are not always obvious without a proper inspection. A PPI gives you an accurate picture before you commit.

What to do with the results
If the inspection is clean, buy with confidence. If it finds problems, use the report to negotiate a lower price or walk away. The cost of an inspection is small compared to the cost of buying a vehicle with hidden issues.
