Have you driven a diesel? Are you sure you want to go this route? With that mileage I would only buy if you have service records, as with my 300 D. There are other issues with the miles regardless of how well the car was cared for â€“ suspension and front end problems, ACC issues, leaking seals, overheating, and transmissions problems. A knowledgeable MB mechanic should check the car bumper to bumper. I would also have a compression test done.
