2018 Mercedes-Benz C 1.9L Diesel · AM13 AMM

A clean and stable MOT trajectory defines this 2018 Mercedes-Benz C-Class, with four consecutive passes recorded between November 2021 and March 2026 and no failures, refusals, or advisories of a structural or safety-critical nature ever logged against the vehicle. The most recent examination on 19 March 2026 was passed without any defects recorded, continuing an unbroken run of clean outcomes that stretches back through the October 2024, November 2022, and October 2021 tests. The only blemishes on the file are two advisories issued at the 2021 test concerning both rear tyres being worn close to the legal limit on the inner edges, and a matching advisory at the November 2023 test flagging the same condition on the rear tyres once again. Because the same axle has been highlighted twice across an eight-year testing history, the rear tyre inner-edge wear pattern is the single recurring mechanical theme worth investigating, while the absence of any suspension, brake, corrosion, exhaust, or lighting advisories across the entire record is a positive indicator of overall structural and component health. Against an age of roughly eight years, the recorded mileage of 86,184 miles equates to an annual accumulation of approximately 10,773 miles, which sits broadly within expected parameters for a private or light commercial use of this model and indicates a vehicle that has been driven consistently rather than left standing for prolonged periods. Testing has taken place regularly on an almost annual basis, with intervals of around twelve months separating each examination, and the mileage progression between tests appears steady rather than subject to sudden spikes or extended gaps. There is no evidence of the car having been laid up for multiple consecutive years, which removes the typical concerns around seized brakes, deteriorated fuel, perished coolant hoses, and stagnant 12V battery conditioning that can accompany long periods off the road. The continuous usage profile means the consumable wear items such as brake pads, discs, tyres, and drive belts will have been subjected to normal service intervals rather than age-related degradation without use. Given the repeated rear-tyre inner-edge advisories recorded in both 2021 and 2023, a prospective buyer should pay particular attention to the rear suspension geometry during any inspection, as this wear pattern on a Mercedes-Benz of this era is frequently linked to worn rear suspension components rather than simply tyre age. Specific items to examine include the rear trailing arm bushes, the lower control arm bushes, the rear subframe mounting bushes, and the condition of the coil springs, all of which can deteriorate and allow camber to drift towards negative on the inner shoulder. On a test drive, listen for clonking or knocking noises from the rear axle when traversing speed bumps, expansion joints, or uneven tarmac, and feel for any vagueness or delay in the rear end's response during direction changes. With the vehicle unladen, push down firmly on each rear corner and release it, observing whether the body settles promptly and without a secondary oscillation that could indicate weakened dampers or strut mount wear. The braking system also warrants a focused assessment on the test route, even though no brake-related advisories have ever been recorded. With 86,000 miles accumulated, the front brake discs and pads are likely to be approaching the point where a replacement is due, so any deep scoring, lipping on the disc edges, or a spongy or low pedal should be noted. Under gentle braking from around 30 mph, check for any judder through the steering wheel or pedal, which would suggest disc run-out or warped friction surfaces, and listen for any grinding or metallic scraping that could indicate pad material worn down to the backing plate. A final check of the rear tyre inner edges against a known-good reference, along with a four-wheel alignment read-out from a specialist, would confirm whether the geometric cause of the previous advisories has been resolved or remains an unresolved underlying issue.
