2013 Mercedes-Benz C 2.1L Diesel · DE63 AEO

The most recent MOT history demonstrates a stable roadworthiness trend, though the vehicle’s December 2025 test cycle reveals an unusual double entry—one pass and one immediate fail at nearly identical mileages (97,893 and 97,894). Since no defects were recorded in either instance, this anomaly suggests either a temporary administrative error or a test centre oversight rather than a mechanical issue. The preceding tests in September 2024 and September 2023 both passed without advisories, indicating consistent compliance with MOT standards over the past two years. However, the lack of any recorded defects across five tests does not preclude underlying wear, particularly in high-mileage components like suspension bushes or brake calipers, which may not always trigger a fail but could degrade over time. The vehicle’s recorded mileage of 97,894 miles at the latest test aligns with typical usage for its age, averaging around 7,500 miles annually. There are no significant gaps in the MOT history, and the mileage progression between tests remains steady—ranging from 7,000 to 8,000 miles between each September-to-September interval. This consistency suggests the vehicle has not been left unused for extended periods, which could otherwise accelerate corrosion or fluid degradation. That said, the absence of advisories in any test means there is no evidence of recurring issues, though this does not guarantee all maintenance has been diligently performed. Given the lack of recorded defects, a buyer should prioritise a thorough inspection of suspension components, particularly the rear bushes and coil springs, which are prone to fatigue at this mileage. The brakes, while not explicitly failed, should be checked for uneven wear or binding calipers, as these often develop gradually without triggering an MOT fail. Examine the underbody for corrosion, especially around the sills and wheel arches, as this can compromise structural integrity. Finally, verify the condition of the exhaust system for leaks or damage, as catalytic converter failures are common in this model range and may not always be detected during a standard MOT. The double test in December 2025, though unexplained, warrants scrutiny of the vehicle’s service history to confirm whether any critical maintenance was overlooked.
