Our Verdict
Proceed with extreme caution unless you are a specialist or a high-mileage enthusiast. While the vehicle has survived many years, the extreme mileage is far beyond the typical threshold for a road car.
The primary focus here must be on the service history. At over 440,000 km, you need to verify that critical components such as the turbocharger, fuel injectors, and cooling system have been maintained or replaced proactively. Ask for a comprehensive folder of receipts; any gap in the records is a major red flag for an engine of this size.
Negotiate based on the inevitable wear and tear associated with such high mileage. Many rubber components, bushings, and seals will likely be perished or leaking. Ensure the vehicle is tested cold to check for any unusual smoke or heavy engine knocking, which could indicate internal wear in the large 4.2L diesel unit.
Running costs will be significant due to the large 4250.0cc engine displacement. Expect fuel economy to be much lower than modern diesels, and annual road tax will likely fall into a high bracket due to the engine size and emissions profile.
Maintenance is also expected to be costly as parts for older large-capacity Mercedes can be specialized and expensive. You should budget a substantial emergency repair fund, as the probability of a major component failure (such as transmission or suspension) is statistically high at this mileage.
Review the MOT failure from January 2022 at 427,758 miles; although the specific reason isn't listed in the summary, it indicates a period where mechanical standards were slipping. Inspect for heavy oil leaks around the head gasket and turbo, which are common on high-mileage units.
Pay close attention to the suspension and tyres. Given the weight of the vehicle and the mileage, the control arms, shocks, and bushings will be under immense stress. Check for any signs of rust on the undercarriage that may have accumulated over decades of use.
This 2001 Mercedes is powered by a massive 4.2L diesel engine and has covered a staggering 442,940 km over its life. While it has maintained a consistent record of passing MOTs in recent years, the sheer mileage suggests components are likely nearing the end of their functional life. It represents a high-risk investment where the value is driven more by its utility or enthusiast status than long-term reliability.
No aggregate data is available for this specific model variant, but large-displacement Mercedes dies of this era are known for requiring meticulous maintenance.
