2005 Mercedes-Benz C 2.7L Diesel · SK05 ACX

The vehicle failed its most recent MOT on 2023-08-25 at 127,296 miles, with multiple critical issues including structural corrosion, brake system irregularities, and suspension component faults. The recurring nature of problems such as anti-roll bar bracket damage, brake disc wear, and underbody corrosion suggests a worsening maintenance trend rather than stable condition. Key failures like the offside front seat belt anchorage weakness and fluctuating brake performance indicate potential safety risks that require immediate attention. Mileage progression shows consistent annual usage of ~6,062 miles, aligning with typical patterns for a 21-year-old vehicle. However, the 2022-05-27 test revealed minor corrosion and anti-roll bar damage, which were not resolved by the 2023 failure. A gap between the 2022-05-20 failure and subsequent 2023 test may suggest delayed repairs, while the 2020-03-27 and 2021-05-24 tests recorded manageable issues like tyre wear and minor suspension play. The absence of recent tests beyond 2023 raises questions about ongoing maintenance compliance. A buyer should prioritize inspecting the suspension system for worn bushes, anti-roll bar brackets, and steering rack play, as these components repeatedly failed or were flagged. Brake discs, pads, and calipers require thorough examination for uneven wear or binding, given the consistent reports of pitting and fluctuating performance. Structural corrosion, particularly in the inner sill area and sub-frame, demands close scrutiny for integrity, as it may compromise safety. The oil leak and exhaust heat shield issues also warrant verification to assess fluid system health and potential long-term damage.
