Inspect for rust, fresh undercoating, mismatched paint, uneven panel gaps and any sign of prior collision or frame repair.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Forward Collision Avoidance
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
