2018 Mercedes-Benz C 3.0L Petrol · MM12 DOC

The most recent DVSA MOT test on 20 October 2025 was recorded as a pass with no defects or advisories noted, which is a positive immediate indicator for any prospective purchaser. Reviewing the wider pattern across the documented history, the overall maintenance trend is best described as broadly stable but with notable intermittent concerns rather than a clear trajectory of either improvement or deterioration. The vehicle has recorded five passes since 2021 alongside two failures and several advisories, with the most recent test demonstrating that prior flagged issues, particularly the fluid leaks from the suspension, appear to have been addressed. However, a closer reading reveals recurring themes relating to rear tyre wear on the inner edges, which has been flagged on more than one occasion, suggesting this may be a persistent characteristic of the vehicle's geometry or alignment settings that warrants further investigation. With a recorded mileage of 52,079 miles over approximately eight years, this C-Class is averaging around 6,500 miles annually, which sits comfortably within typical expectations for a vehicle of this age and class. There are no significant gaps in the MOT record that would suggest extended periods of standing, nor is there any evidence of rapid mileage accumulation that would point to heavy commercial or high-mileage use. This moderate usage profile is mechanically favourable, as it implies that major drivetrain and engine components should not be excessively worn, although consumable items such as brake discs, pads, and tyres will still have experienced normal service life wear proportional to the cumulative mileage. The relatively even annual distribution also suggests the vehicle has been used consistently rather than subjected to long idle periods that can promote certain age-related deterioration concerns. Given the recurring advisories on the rear tyres showing uneven inner edge deterioration, a thorough physical inspection of the current set of tyres is strongly advised. Inner edge wear of this nature is commonly symptomatic of either rear wheel alignment issues, such as incorrect camber settings, or potentially worn suspension components including rear bushes, coil springs, or shock absorber mounting points. The history of fluid leaks from both offside front and offside rear shock absorbers across different test dates, while apparently rectified, indicates the vehicle may be approaching the end of its original suspension damping life, and any test drive should include careful listening for clonking or knocking noises from the suspension over uneven surfaces, as well as attention to any excessive body roll or pitching through corners. The previous failure related to a cut in the nearside rear tyre deep enough to reach the ply or cords also highlights the importance of inspecting all four tyres for adequate tread depth and sidewall integrity, with replacement of all four tyres being a realistic budgeting consideration. Beyond the documented MOT findings, prospective buyers should conduct a comprehensive physical inspection befitting the vehicle's age and mileage profile. Brake discs should be examined for lipping and corrosion, particularly given the moderate usage, and calipers should be checked for binding or seized slider mechanisms that can cause uneven pad wear. The 12V battery, now approximately eight years old, is likely approaching the end of its reliable service life and should be load tested prior to purchase. All vehicle fluids, including engine oil, coolant, brake fluid, and automatic transmission fluid if applicable, should be verified as recently serviced, as brake fluid is particularly susceptible to moisture absorption over time and benefits from biennial replacement regardless of mileage. The exhaust system should be inspected for corrosion at mounting points and joints, and the underside examined for any oil leaks from engine or transmission seals that would not necessarily be captured in an MOT test. Finally, verifying a complete service book history with appropriate stamp intervals will provide confidence that the vehicle has been mechanically maintained to manufacturer schedules throughout its life.
