2015 Mercedes-Benz C 2.1L Diesel · KT64 ATK

The vehicle’s most recent MOT test on 2025-08-27—just under a year ago—shows a clean pass with no defects recorded, though it is unusual to have both a pass and a fail entry for the same test date and mileage. This anomaly suggests either an administrative error or a rare instance of a vehicle being tested twice in quick succession for unrelated reasons. The preceding MOT in 2024-08-30 also passed without failings, indicating a stable maintenance history over the past two years. However, the lack of any advisories or recurring faults in the record does not guarantee hidden issues, particularly given the vehicle’s age and low mileage. The recorded mileage of 40,741 miles over approximately 11 years—roughly 3,700 miles annually—is unusually low for a vehicle of this age, suggesting either minimal use or prolonged periods of inactivity. The gaps between tests are consistent, with roughly 5,000 miles covered between each MOT, which aligns with typical annual mileage for a lightly used car. There is no evidence of rapid mileage accumulation or abrupt changes in usage patterns, which could have indicated aggressive driving or deferred maintenance. However, low mileage does not preclude wear from age-related factors such as suspension degradation, brake pad consumption, or minor corrosion. Given the lack of recorded defects, the most critical areas for an in-person inspection should focus on components that often fail silently or deteriorate over time despite low mileage. The suspension system—particularly coil springs, bushes, and dampers—should be examined for uneven wear, fluid leaks, or excessive play, as these can develop even with minimal use. Brake discs and calipers warrant close scrutiny, especially if the vehicle has experienced extended periods of disuse, as moisture and corrosion can accelerate wear. Structural integrity, including underbody corrosion and body panel rigidity, should also be assessed, particularly around wheel arches and sills, where salt and moisture accumulate over time. Finally, the exhaust system’s integrity should be checked for leaks or rust, as these are common failure points in older Mercedes-Benz models. While the MOT record provides reassurance, these areas demand thorough visual and functional verification.
