2012 Mercedes-Benz C 2.1L Diesel · SK04 AMO

The vehicle is currently roadworthy but exhibits a concerning trend in mechanical wear and structural neglect. While it passed its most recent test in March 2026, it failed immediately prior due to multiple safety-related defects including tyre wear and suspension play. The transition from a significant failure to a pass at the same mileage suggests that essential repairs are being made when forced, but the overall condition of the vehicle indicates a reactive rather than proactive maintenance strategy. At 172,668 miles, this 2012 Mercedes-Benz has averaged approximately 12,333 miles per year. This represents consistent high-mileage usage over its lifespan, which explains the accelerated degradation of components like bushes and discs. Between April 2024 and April 2025, the car covered roughly 4,300 miles, a period during which persistent oil and coolant leaks were noted, suggesting that the seals and cooling systems are under significant stress due to the high mileage. A prospective buyer must prioritise a thorough inspection of the underbody and structural integrity. The April 2025 failure highlighted a nearside rear sub-frame that was corroded and seriously weakened, resulting in a broken suspension arm mounting; this is a critical structural fault that requires verification to ensure the repair was robust and safe. Furthermore, the recurring issues with worn suspension arm bushes and play in the front track rod ends indicate that the entire suspension geometry is nearing the end of its functional life. The braking system also requires close attention, as records show pitted and scored discs alongside a parking brake that only just barely met efficiency standards in 2025. Combined with the history of oil and coolant leaks, the engine bay should be inspected for signs of active weeping that could lead to component failure. The recent failure for uneven tyre wear on the front tackle further suggests an alignment issue or worn dampers that must be addressed to prevent immediate replacement of new rubber.
