2007 Mercedes C 2.1L Diesel · BO53 RJP

The vehicle remains roadworthy but the maintenance history indicates a worsening trend regarding structural corrosion and component degradation. While the car passed the September 2023 test at 140,962 miles, the tester identified significant corrosion on both front and rear brake pipes, which were further obscured by grease. This suggests an attempt to mask surface rust or ongoing issues that have not been professionally addressed. The appearance of corrosion on the nearside rear sub-frame, though not yet seriously weakened, marks the beginning of structural integrity concerns that require close monitoring. At 19 years old, the recorded 140,962 miles average to approximately 7,400 miles per year, which is consistent with typical UK usage for this age. The mileage progression shows steady use, with roughly 6,400 miles driven between the 2022 and 2023 tests and over 11,000 miles in the preceding year. However, the failure in September 2020 due to missing wheel fixings and worn brake pads indicates a period where basic pre-inspection checks were neglected despite the annual test interval. A buyer must conduct a thorough physical inspection of the chassis, specifically focusing on the nearside rear sub-frame to determine if the rust has progressed beyond surface levels. The recurring issue with defective exhaust mountings in 2022 and 2023 suggests the exhaust system is loose and may soon require replacement rather than simple repair. Furthermore, the deteriorated anti-roll bar ball joint dust covers noted in 2022 indicate that suspension rubber components are reaching the end of their service life. Given the corroded brake pipes, a professional check of the hydraulic lines is essential to ensure there is no thinning or imminent leakage that could lead to brake failure.
