💥 1 involved a crash 🔥 1 involved a fire
🔍 Listen for knocks or ticking, check for leaks and blue/white exhaust smoke, and make sure it doesn't overheat. No check-engine light should be on.
🔍 Check for fuel or battery warnings, hard starts and stalling. On a hybrid/EV, confirm charging and range behave normally.
🔍 Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
🔍 Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
🔍 Test cruise control and throttle response, and watch for any hesitation or unintended acceleration.
🔍 Steering should be tight and centered — no play, clunks or wandering. Test at low and highway speed; listen for power-steering whine.
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.

I DID SOME RESEARCH ON MERCEDES 3.0L DIESEL MOTORS AND THERE SEEMS TO BE AN ISSUE WITH THE SEAL FAILING ABOUT 50,000 MILES CAUSING THE MOTOR TO LEAK OIL AND THE SEAL AS WELL AS THE OIL COOLER NEED TO BE REPLACED. IT IS SUCH A COMMON PROBLEM ON THE 3.0L DIESEL ENGINES THAT WHEN YOU CALL ANY REPAIR SHOP THE FIRST THING THEY ASK IS IF THE CAR IS A DIESEL. ALSO …
