Exterior Lighting
Confirm all headlights, brake lights, turn signals and reverse lights work, with no moisture inside the housings.
Electrical System
Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
Steering
Steering should be tight and centered — no play, clunks or wandering. Test at low and highway speed; listen for power-steering whine.

Latches/locks/linkages
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Vehicle Speed Control
Test cruise control and throttle response, and watch for any hesitation or unintended acceleration.
