Seat Belts
Check that every belt latches, retracts and locks under a sharp tug, and that none are frayed.
Seats
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
Lane Departure
Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
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.
