2011 Mercedes-Benz C 2.1L Diesel · RJ11 LFA

The vehicle presents a concerning roadworthiness profile with a clear trend of worsening structural and mechanical degradation. While it passed its most recent MOT in October 2025 at 164,326 miles, this followed a significant failure just three days prior. The tester identified the rear sub-frame as seriously corroded and weakened, which is a critical structural safety risk. Although the vehicle currently holds a certificate, the presence of extensive brake pipe corrosion and wheel bearing play suggests the car is reaching a stage of high-maintenance requirements. At 164,326 miles, this 15-year-old Mercedes has covered an average of approximately 11,000 miles per year, which is consistent with typical annual usage for its age. The mileage data shows consistent use between tests, with roughly 9,000 miles covered between September 2024 and October 2025. However, the high mileage has clearly accelerated the decay of rubber-based components, particularly the suspension bushes and shock absorbers, which have appeared as as recurring points of failure over the last three years of inspections. A buyer must conduct a rigorous physical inspection of the rear sub-frame to ensure the structural repairs following the October 2025 failure were competent and comprehensive. The record shows a persistent issue with brake pipe corrosion across multiple locations, often masked by grease, which may indicate an attempt to hide surface rust rather than replace the affected lines. Furthermore, the front wheel bearings were flagged for both play and noise in the latest test, indicating these components are nearing imminent failure. The suspension system shows signs of age, with perishing bushes on the control arms and anti-roll bar linkages noted in previous years. Given the history of reduced damping in the front shock absorbers, the vehicle likely requires significant investment in suspension components to maintain original handling standards. The buyer should verify that the corrosion noted on the inner wheel arches and undertrays has not spread to the main chassis structure.
