2015 Mercedes-Benz C 2.1L Diesel · DF65 XRH

Five consecutive clean passes with not a single advisory or failure recorded defines this 2015 Mercedes-Benz C-Class as an unusually consistent performer at test, with the latest examination on 26 November 2025 continuing an unbroken run of defect-free results stretching back to December 2021. For a car now eleven years old, the complete absence of even minor advisories across five successive tests is notable, since vehicles of this age and mileage typically begin accumulating observations on suspension bushes, brake component wear, or minor corrosion. The trend is stable and unblemished, with no historical failures to suggest recurring problem areas or deferred rectification work. The recorded mileage of 123,752 miles equates to roughly 11,250 miles per year, which sits squarely within the expected range for a vehicle of this age and suggests regular, sustained use rather than long periods standing idle. Annual testing has occurred consistently each December, with the most recent test shifting slightly earlier to late November, and there are no gaps in the record that would indicate time off the road. This pattern of steady accumulation is generally favourable mechanically, as components such as brake discs, suspension joints, and drivetrain parts benefit from regular operation rather than the deterioration associated with prolonged inactivity, though the mileage does mean wear items will have seen genuine service life. Given the clean test history, the buyer's focus should shift to verification rather than hunting for known defects. At this mileage on a C-Class, particular attention should be paid during a test drive to the suspension and steering: listen for knocks or clonks over uneven surfaces that could indicate worn front control arm bushes or drop links, and check for any vagueness or pull in the steering that might suggest wear in track rod ends. Brake pedal feel should be firm and progressive without judder through the pedal or steering wheel under moderate braking, which would point to disc wear or runout not yet severe enough to attract an advisory. It is also prudent to inspect areas that MOT testing does not fully cover. Check the engine for oil misting around the rocker cover and turbocharger plumbing, examine the condition of the automatic transmission fluid if service records permit, and confirm smooth, timely gearchanges both cold and warm, as transmission behaviour is outside the scope of the annual test. Service history documentation becomes especially valuable here, since a clean MOT record confirms roadworthiness at each test point but says nothing about adherence to scheduled maintenance such as oil changes, brake fluid renewal, and coolant replacement. A well-documented service file alongside this exemplary test record would make a strong case for purchase.
