2006 Mercedes-Benz C 1.8L Petrol · LR56 KKL

The most recent MOT test on 2025-10-16 confirms the vehicle passed without defects, though it follows an unusual sequence of two consecutive tests—one failure and one pass—both at the same mileage of 38,915 miles. This pattern suggests either a procedural anomaly in the test centre or a brief, unresolved issue that did not recur at the time of the subsequent pass. The overall trend remains stable over the past two years, with no recurring faults or advisories recorded in any of the five tests since 2023. However, the failure on 2025-10-14, despite no defects being logged, raises a question about what specific condition prompted the rejection, which is not documented in the public record. The recorded mileage of 38,915 miles over nearly 20 years equates to an exceptionally low annual average of around 1,946 miles, well below the typical UK usage for a vehicle of this age. This suggests the car has spent extended periods either in storage or under light use, which could mitigate some wear-and-tear concerns but does not eliminate the need for thorough inspection of components prone to degradation over time. Notably, there is a 5,373-mile gap between the 2023 and 2024 tests, followed by a rapid accumulation of 1,051 miles in just over a month before the 2024 failure. While this does not indicate aggressive driving, it does imply the vehicle was actively used during that period, which may have stressed certain systems. Given the lack of documented defects, a buyer should prioritise an independent inspection of high-wear items not typically flagged in MOTs, such as suspension bushes and coil springs—particularly rear, where binding has been a historical concern in this model. The absence of advisories does not preclude corrosion in wheel arches, subframes, or sills, especially given the vehicle’s age; rust in these areas can compromise structural integrity without immediate failure. Additionally, the brakes—though not explicitly failed—should be scrutinised for uneven wear, glazing, or binding, as the 2025 failure suggests a potential underlying issue. Finally, the exhaust system and emissions controls warrant attention, as older Mercedes-Benz models are prone to catalytic converter degradation or exhaust leakages over time, which may not always surface in a standard MOT.
