2018 Mercedes-Benz C 2.0L Petrol · RO18 WOX

A recurring theme of premature and uneven tyre wear runs through the entire MOT history of this 2018 Mercedes-Benz C-Class, making it the single most significant mechanical indicator on the file. Across four consecutive annual tests from 2022 through 2025, advisories have been raised for tyres on all four corners approaching or below the legal tread limit, with a particularly concerning dangerous failure recorded in April 2021 for a nearside front tyre measuring below the 1.6mm requirement. The 2025 test also flagged sidewall cracking and perishing on both front tyres, suggesting age-related rubber degradation rather than purely mileage-driven wear. While the most recent test on 26 April 2026 returned a clean pass with no advisories, and the only non-tyre failure on record, a missing nearside front road wheel fixing in 2025, was rectified on the same day with a pass, the persistent tyre pattern warrants serious scrutiny as it can indicate underlying alignment, suspension geometry, or steering component issues that a standard MOT inspection does not diagnose. The recorded mileage of 52,241 miles over an eight-year ownership period equates to an average of roughly 6,530 miles annually, which sits within a typical range for a vehicle of this age and class and shows no significant gaps in annual testing. There is no evidence in the MOT record of the vehicle being laid up for extended periods, with continuous annual tests from 2021 through to the present and no unusual jumps or stagnation in the implied mileage progression between tests. This consistent usage pattern should in principle be favourable for preserving component condition, preventing prolonged standing which can degrade brake discs, callipers, suspension bushes, and tyre sidewalls through dry rot and corrosion. The modest annual mileage does, however, mean a higher proportion of short journeys, which historically accelerates corrosion on underbody components such as brake lines, subframe mounts, and exhaust fittings, although no such issues have yet surfaced on the MOT record. For a prospective buyer, the tyre wear pattern should be the primary focus of a physical inspection and test drive. Given the repeated advisories across all four corners, it is essential to have the wheel alignment checked on a four-wheel laser system, as Mercedes-Benz vehicles are sensitive to geometry settings and even slight deviations can produce the kind of shoulder or inner-edge wear recorded here. On a test drive, listen for any knocking or clonking from the front suspension over uneven surfaces, which could indicate worn drop links, control arm bushes, or top mount bearings, and pay particular attention to steering behaviour including any pulling to one side, vibration through the wheel, or uneven self-centring, all of which would suggest worn suspension linkages. The rear tyres have been flagged repeatedly for edge wear, so check for a firm, level ride quality without excessive float or secondary ride movement, which could point to Bilstein or coil spring degradation. Brake-related scrutiny is also warranted, as the 2022 test noted rear brake pads wearing thin, although no subsequent advisories have appeared for the friction material itself. On the road, the brake pedal should feel firm and progressive without excessive travel, and the vehicle should stop squarely without any pulling to either side, which would suggest a binding caliper or a sticking rear caliper slide mechanism. Given that no brake disc or pipe corrosion advisories have yet been recorded, this remains an area of latent risk that tends to manifest as annual mileage accumulates or as the vehicle is used predominantly for short urban journeys where moisture is not burnt off the discs through sustained braking. Finally, the failed road wheel fixing from 2025 should be confirmed as properly torqued with no signs of stripped threads or distortion to the wheel bore, and a thorough inspection of the underbody, subframe, and brake line ferrules is recommended to ensure no corrosion has developed in areas not visible during the standard MOT procedure.
