2020 Mercedes-Benz C 1.9L Diesel · LM70 EFW

The most recent MOT, conducted on 26 September 2024 at 45,038 miles, passed, but the record reveals a worsening mechanical trend in the twelve months prior. The vehicle failed its initial test on 25 September 2024 with multiple critical tyre defects and brake wear, all of which were rectified before the pass the following day. Front brake discs were flagged as worn, and pads were noted as thin across both attempts. This pattern suggests the braking system is approaching the end of its serviceable life and requires ongoing monitoring. Mileage accumulation stands at approximately 7,500 miles per year, which is typical for a six-year-old executive saloon. The recorded distance jumped from 33,676 miles in September 2023 to 45,038 miles by September 2024, representing an 11,362-mile increase in a single year. That is notably higher than the annualised average and points to a period of heavier use, likely motorway commuting or long-distance driving, which accelerates wear on consumables like brake discs, pads, and tyres. The September 2024 failure exposed serious tyre deterioration, including exposed cords on both front tyres and a rear tyre below the 1.6mm legal minimum. Exposed ply or cords indicates prolonged neglect of tyre condition and alignment, raising questions about whether the suspension geometry or tracking has been checked. Buyers should inspect the inner edges of all four tyres closely and verify whether a four-wheel alignment has been performed, as uneven inner wear often points to worn suspension bushes, tracking misalignment, or damaged wishbone components. The recurring front brake advisories, combined with the sudden spike in annual mileage, suggest the braking system has endured significant thermal and frictional stress. A physical inspection should include measuring remaining pad material, checking disc thickness and condition for scoring or lipping, and testing the handbrake function. Given the exposed cords flagged just months ago, the entire underside, including shock absorbers, coil springs, and subframe mounting points, warrants a thorough inspection for corrosion or impact damage before purchase.
