Always inspect a vehicle thoroughly, even if you are buying from a reputable dealership.

The Cold Start: Always ask the seller not to warm up the car before you arrive. A cold engine reveals knocks, rattles, and smoking exhaust that a warm engine hides.
Fluid Checks: Oil should be amber or black (but not milky). Transmission fluid should be pink/red and not smell burnt.
Panel Gaps: Inconsistent spacing between the hood, fenders, and doors indicates poorly repaired accident damage.
