Practical Used-Car Buying Guide: Inspection and Test Drive
Verify the vehicle's identity first
Confirm that the VIN, registration, mileage history, service records, and repair documents are consistent. Be cautious when the source is unclear, key records are missing, or the price is unusually low.
Inspect structure and repair evidence
Paint variation alone does not prove a major crash, but unusual repairs around frame rails, strut towers, sills, or factory welds deserve professional inspection. Check for uneven tire wear, leaks, and underbody impact.
Use varied test-drive conditions
Listen during a cold start, test steering and braking at low speed, and assess stability, noise, and vibration at higher speed. Recheck warning lights and fluid leaks after the drive.
