2013 Mercedes-Benz C 6.2L Petrol · DF13 ORA

The vehicle most recently passed its MOT on 27 April 2026, though it was issued with two advisories that warrant attention. One relates to light oil misting on the nearside rear shock absorber, a condition that has now been flagged on two consecutive tests in 2025 and 2026, suggesting the seal is gradually weeping hydraulic oil. The second advisory notes that the rear parking brake efficiency only just met the required standard and would benefit from adjustment or repair. Despite these advisories, the overall MOT history shows a stable pattern of passes with only one recorded failure in March 2023, which was attributed to a fractured nearside front coil spring along with an advisory regarding a binding nearside rear service brake. The fact that the car has consistently passed since that single failure, combined with the absence of any structural or corrosion-related defects across the entire test record, indicates a generally sound and well-maintained vehicle rather than one displaying a worsening mechanical trend. With a recorded mileage of 41,115 miles across approximately 13 years, this Mercedes-Benz C-Class has covered an average of around 3,160 miles annually, which is notably low for a vehicle of its age. Such modest usage is typical of second cars, short urban journeys, or vehicles that may have experienced extended periods of standing. The MOT history supports this picture, as there is a gap between the 2019 and 2021 entries and again between 2022 and 2023, suggesting the vehicle was not necessarily in continuous active use. Low annual mileage carries its own mechanical considerations, as standing can accelerate certain forms of degradation such as brake disc corrosion, caliper binding, tyre sidewall perishing, and 12V battery deterioration, all of which are time-dependent rather than purely mileage-dependent. For a prospective buyer, the recurring nearside rear shock absorber oil misting should be inspected physically by checking the shock body for fresh oil residue and confirming the damper still operates smoothly without excessive bounce. On a test drive, listen for clonking or knocking noises from the rear suspension over uneven surfaces, which would suggest the shock is nearing the end of its service life. The 2026 advisory regarding marginal rear parking brake efficiency warrants a thorough check of the caliper mechanism, handbrake cable, and rear brake adjustment, as a binding or poorly adjusted parking brake can lead to uneven rear brake pad wear, brake drag, and potential overheating. Additionally, although the front coil spring fracture in 2023 was rectified to achieve the subsequent pass, it would be prudent to check the condition of the opposite nearside front spring and inspect all suspension bushes, drop links, and wishbone components for play or wear, as fractured springs can sometimes indicate broader suspension fatigue. Given the low mileage and the age of the vehicle, several time-based inspections are advisable beyond the MOT record. The tyres should be examined closely for sidewall cracking and perishing, as rubber degrades with age regardless of tread depth, and this is a particular concern for a 13-year-old vehicle. The brake discs and calipers should be checked for surface corrosion and seized slider pins due to potential periods of standing, and a thorough road examination should confirm the brakes release cleanly without any dragging sensation. The 12V battery should be tested for its state of health, as batteries that have sat partially discharged suffer reduced lifespan. Finally, it would be sensible to confirm the timing of the most recent service, ensuring that brake fluid, coolant, and transmission fluid have been changed in accordance with calendar-based intervals, as calendar-aged fluids lose effectiveness and may warrant replacement purely on the basis of the vehicle's age rather than its modest mileage.
