Quick note: This guide helps you understand the issue and prepare for service. It is not a vehicle-specific diagnosis.
1

Start with identity and history

Confirm the VIN on the vehicle matches the paperwork. Review available history, title information and seller disclosures before becoming emotionally committed to the car.

2

Check the warning lights correctly

All expected warning lamps should illuminate during the key-on self-test and then behave normally after startup. A missing or permanently illuminated lamp deserves investigation.

3

Look, listen and smell

Check for fluid leaks, uneven tire wear, smoke, unusual engine noise, water or mildew odor, mismatched paint and signs of rushed body repair.

4

Still get an independent inspection

A quick buyer check is not a substitute for lifting the vehicle, scanning systems, measuring wear and performing an appropriate road test before purchase.
