2017 Mercedes-Benz C 2.1L Diesel · KS67 VEH

This Mercedes-Benz C has demonstrated consistent MOT compliance over the past three years, with the most recent test on 16 March 2026 at 79,425 miles confirming no defects and a clean pass. The absence of advisories or repeated failures across all tests suggests the vehicle has been maintained at a basic level, though the record does not reveal whether routine servicing was performed. The single failure in May 2025—recorded at 68,961 miles—was unusually close to the preceding pass at 68,968 miles, indicating either a rushed inspection or a minor oversight rather than a systemic issue. The pattern remains stable, with no evidence of worsening mechanical trends, but the lack of advisories also means critical components may not have been scrutinised beyond the MOT’s basic thresholds. The mileage progression of approximately 8,825 miles annually aligns with typical usage for a vehicle of this age, though the gap between the 2025 failure and pass—just seven miles apart—stands out as anomalous. The 2023 to 2024 interval shows a steady increase from 40,944 to 56,481 miles, suggesting consistent driving habits, while the jump from 56,481 to 68,968 miles between May 2024 and May 2025 implies either a period of higher mileage or a lapse in recording. There are no red flags in the mileage itself, but the abrupt failure followed by an immediate retest warrants closer scrutiny of whether the vehicle was driven between tests or if the failure was procedural rather than mechanical. Given the clean MOT history, a buyer should prioritise a thorough inspection of high-wear components that are not routinely checked during an MOT. The suspension—particularly rear bushes and coil springs—should be examined for uneven wear or corrosion, as these are common failure points in Mercedes-Benz models of this era. Brake calipers and discs, while not flagged, may exhibit uneven wear or binding, especially if the vehicle was driven between the 2025 failure and retest without servicing. Structural integrity, including underbody corrosion and subframe connections, should also be assessed, as these are not tested during an MOT but can pose long-term risks. Finally, the exhaust system and emissions should be visually inspected for leaks or damage, as these are often overlooked until they fail an MOT. The absence of advisories does not guarantee these areas are sound, so a professional inspection is advisable.
