2007 Mercedes C 320 3.0L Diesel · SN57 VHP

The vehicle presents a concerning roadworthiness profile with a worsening trend in structural and mechanical integrity. While it passed its most recent test in June 2023 at 167,100 miles, this followed a significant failure just two weeks prior at 166,956 miles. That failure revealed a critical structural defect, with the rear subframe being corroded and seriously weakened. Although the subsequent pass noted the corrosion on the subframe mounting was not excessive, the transition from a dangerous failure to a pass suggests the vehicle is reaching the limit of structural viability. The recorded mileage of 167,100 miles over 19 years reflects an average usage of approximately 8,800 miles per year, which is consistent with a vehicle of this age. However, the data shows a significant gap in testing history between June 2022 and June 2023 where the car covered over 16,000 miles in a single year. Given that the current date is June 2026, the vehicle has not had a recorded MOT test in three years. This long interval leaves the current state of the chassis and safety components unknown and increases the risk that undetected corrosion or mechanical wear has progressed significantly. A buyer must prioritize a thorough physical inspection of the rear subframe and suspension mounting points, as these areas showed a history of structural decay and wear. The record repeatedly flags corrosion on the front brake pipes between 2021 and 2023, indicating a systemic issue with rust resistance that could lead to sudden brake line failure. The anti-roll bar ball joints and bushes were also noted as having play or wear in 2023, suggesting that the front suspension assembly is nearing the end of its service life. Furthermore, the persistent presence of an oil leak noted across multiple tests indicates a long-term engine issue that requires investigation to ensure it is not accelerating.
