2012 Mercedes-Benz C 6.2L Petrol · R55 KBR

The vehicle’s most recent MOT test on 2025-12-08 confirms it remains roadworthy, though the immediate preceding test on 2025-11-26—just 13 days earlier—resulted in a failure without recorded defects. This abrupt reversal suggests either a temporary administrative oversight or a minor, non-critical issue that was rectified between tests. The pattern over the past two years shows no recurring mechanical failures, with all tests passing except for the two consecutive failures in late 2023, which were likely tied to the same underlying issue. The absence of advisories or repeated faults indicates the vehicle has not experienced progressive wear in suspension, drivetrain, or structural components. However, the lack of defects in the failed tests raises suspicion—either the tester overlooked critical items or the vehicle was driven briefly post-failure before retesting. The recorded mileage of 48,173 miles at the latest test reflects an exceptionally low annual average of approximately 3,441 miles over the vehicle’s 14-year lifespan. This suggests minimal use, which could imply long periods of storage or limited driving conditions. The gap between the 2023 and 2024 tests—spanning 16 months with only 9,181 miles logged—further supports this pattern. While low mileage typically correlates with reduced wear on high-stress components like brakes and suspension, it also increases the risk of neglected fluid changes, corrosion from prolonged inactivity, and degraded rubber elements such as seals and hoses. The absence of mileage spikes or irregular intervals does not immediately indicate poor maintenance, but it does warrant scrutiny of fluid levels and condition upon inspection. Given the sparse defect history, the primary focus for an in-person inspection should centre on components prone to deferred maintenance in low-mileage vehicles. Check for corrosion in wheel arches, sills, and underbody, particularly around the exhaust system and suspension mounts, as prolonged standing can accelerate rust. Examine the condition of brake calipers, pads, and discs for uneven wear or binding, though the lack of brake-related advisories suggests this area may be intact. Inspect suspension bushes, coil springs, and shock absorbers for cracking or excessive play, as these are often overlooked in lightly used cars. Finally, verify the integrity of the exhaust system for leaks or damage, especially if the vehicle was stored in damp conditions. The absence of advisories does not preclude hidden issues, so a thorough mechanical assessment is essential.
