2007 Mercedes C 2.1L Diesel · HV57 LFR

The vehicle remains roadworthy but the maintenance history indicates a worsening trend regarding mechanical and structural components. While it passed the most recent test in June 2025 at 144,016 miles, the tester identified multiple advisories that were not present in previous years. The appearance of black smoke from the exhaust during acceleration suggests potential fuel mixture issues or component wear, while the condition of the rear brake discs and tyres points to deferred consumable maintenance. The mileage pattern is consistent with a 19-year-old vehicle, averaging approximately 7,600 miles per year. There is a steady accumulation of roughly 13,000 miles between June 2023 and June 2024, and another 14,000 miles recorded between June 2024 and June 2025. This regular usage suggests the car is driven frequently rather than sitting, yet the lack of clean records in 2021 and 2022 highlights that the vehicle is now entering a phase of accelerated wear due to age-related degradation. A buyer must conduct a thorough physical inspection of the underbody, specifically the rear subframe mounting areas flagged in 2025 for corrosion. Although the tester deemed it not excessive, rust on these Mercedes models often progresses rapidly into structural failure. The recurring issue of corroded brake pipes, noted at both the front in 2023 and the rear in 2024, indicates that the metal lines are thinning from environmental exposure and should be inspected for further decay before it leads to sudden failure. The braking system requires immediate attention as the rear discs are already pitted and scored. Furthermore, the 2025 report notes the nearside and offside rear tyres being near the legal limit and worn on the edges, combined with perishing on the nearside front tyre, suggests an urgent need for a full set of rubber. The black smoke emission should also be diagnosed by a technician to rule out faulty injectors or a failing EGR valve, as this could lead to a future MOT failure for emissions.
