2005 Mercedes-Benz C 2.1L Diesel · KV55 HCY

The vehicle presents a concerning state of roadworthiness characterized by persistent structural corrosion and mechanical degradation. While it passed its most recent test in August 2025 at 135,411 miles, the record reveals a history of recurring faults that remain unaddressed. The maintenance trend is stable in a negative sense, as critical issues like sub-frame corrosion and corroded rear coil springs have appeared across multiple years without resolution. This suggests a reactive approach to repairs focused solely on passing the MOT rather than preventing ongoing mechanical decay. At 21 years old, the recorded 135,411 miles represent an average usage of approximately 6,450 miles per year, which is consistent with typical low-mileage use. However, the data shows a significant jump of over 7,300 miles between July 2023 and July 2024. The critical failure in July 2024, which noted a fractured nearside front McPherson strut and exhaust fumes entering the cabin, indicates that the vehicle was driven under hazardous conditions or suffered significant neglect before the eventual safety-related failures. A prospective buyer must prioritise a thorough inspection of the structural integrity of the rear sub-frame and suspension mounting points. The tester has consistently flagged corrosion in these areas since 2023, and the presence of corroded rear coil springs suggests a high risk of component failure. The braking system also shows signs of poor maintenance, with pitted and scored front discs and corroded brake pipes noted over several years. Furthermore, the report of perishing and cracking tyres in the 2025 test indicates that the rubber components are failing due to age despite the relatively low annual mileage.
