2006 Mercedes-Benz C 2.1L Diesel · KB55 FMK

The vehicle is currently roadworthy but the maintenance history shows a worsening trend regarding suspension and structural integrity. While it passed the latest test in November 2025 at 174,331 miles, the tester flagged a significant volume of advisories related to the front-end geometry. The presence of multiple worn ball joints, perished anti-roll bar bushes, and worn bushes across the front axle indicates that the suspension system is reaching the end of its functional life and requires a proactive overhaul to prevent future MOT failures. At 174,331 miles over 20 years, the vehicle averages approximately 8,700 miles per year, which is consistent with typical usage for its age. The record shows a consistent driving pattern, with 16,557 miles covered between October 2024 and November 2025. This steady mileage suggests the car is used regularly, yet the recurring failures of components such as the exhaust system and parking brake in 2024 indicate that mechanical issues are often only addressed after they fail an inspection rather than through preventative maintenance. A buyer must conduct a thorough inspection of the rear sub-frame, as corrosion was noted as present in November 2025 and had persisted since at least 2023. The corrosion on the rear coil springs and anti-roll bar is a documented trend across three years of testing, suggesting the vehicle is susceptible to environmental damage. Furthermore, the parking brake system has a history of failure in both 2023 and 2024, necessitating a check of the mechanical mechanism and brake cables to ensure the previous repairs were effective and not merely temporary fixes.
