💥 1 involved a crash 🚑 3 reported injuries
🔍 Test wipers, washers, defrosters and all mirrors. Check the windshield for cracks and any camera/sensor for fogging or faults.
🔍 Test cruise control and throttle response, and watch for any hesitation or unintended acceleration.
🔍 Have a trusted mechanic inspect this system as part of a pre-purchase inspection.
🔍 Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
🔍 Check coolant level and color, look for leaks, and confirm the engine reaches normal temperature without overheating.
🔍 Check that every belt latches, retracts and locks under a sharp tug, and that none are frayed.
Pre-purchase checklist
- Match the VIN on the dash, door jamb and title — they must be identical.
- Cold-start the engine; listen for knocks and check for blue or white exhaust smoke.
- Test-drive through all gears at low and highway speed — no slipping, shudder or pulling.
- Confirm every warning light clears at startup (none should stay on).
- Check fluids — oil, coolant, transmission — for level, color and leaks.
- Look underneath for rust, fresh undercoating or signs of collision repair.
- Always get an independent pre-purchase inspection from a trusted mechanic.
