2017 Mercedes-Benz C 3.0L Petrol · KY67 AEV

The vehicle’s most recent MOT test on 2025-09-10—just under a year ago at 54,297 miles—confirms it passed without any defects or advisories. This consistency across all five recorded tests (2021 to 2025) suggests a stable maintenance history with no recurring mechanical failures. The absence of advisories or defects in the latest test implies the tester found no binding calipers, excessive suspension wear, or structural corrosion that would warrant immediate attention. However, the 2021 test at 23,978 miles stands out as an anomaly, with a significant mileage jump of nearly 17,000 miles in just over a year, which could indicate either intensive use or a period of neglect before regular servicing resumed. The mileage progression reveals a pattern of roughly 6,000 miles per year, which is typical for a vehicle of this age. The gap between the 2021 and 2022 tests—where mileage increased from 23,978 to 40,983—is the most notable deviation, spanning nearly 17,000 miles in under a year. While this could reflect heavy usage, it also raises questions about whether critical components like brakes, suspension, or drivetrain were serviced at the appropriate intervals during that period. The subsequent tests show a more consistent mileage accumulation, suggesting the vehicle has been maintained more regularly since then. Given the clean MOT history, a buyer should prioritise an in-person inspection of high-wear areas that aren’t always visible in a test. Focus on the suspension—particularly the rear bushes and coil springs—for signs of dry rot or excessive play, as these components degrade gradually and may not always trigger a fail until they’re critically compromised. The brakes, though never flagged in tests, should be checked for uneven wear or binding calipers, especially if the vehicle has experienced rapid mileage accumulation. Additionally, examine the underbody for corrosion around the sills, wheel arches, and exhaust system, as Mercedes-Benz models of this era are prone to rust progression over time. Finally, verify the condition of the exhaust emissions system, as failing twice on emissions would have been a red flag, though none were recorded.
