2018 Mercedes-Benz C 1.9L Diesel · K10 RAY

The most recent MOT on 13 May 2026 records a failure for the off‑side front lower suspension arm ball joint, classified as excessively worn. This defect breaches the legal requirement for safe road use, meaning the vehicle is not road‑worthy until the ball joint is replaced. The pattern moves from earlier minor tyre advisories to a serious suspension issue, indicating a worsening trend in component condition. Mileage has risen from 17,994 miles on 1 June 2021 to 42,700 miles on 13 May 2026, averaging roughly 5,300 miles per year. Such low annual mileage is consistent with light usage rather than prolonged storage, and the record shows no abrupt spikes or gaps that would suggest periods of intensive driving. The incremental increase aligns with the gradual emergence of faults, rather than a sudden surge in wear. A prospective buyer should give close attention to the front suspension, confirming that the off‑side lower ball joint and associated bushes are free of play and corrosion. Inspect both rear tyres for the cracking or perishing noted in the 2025 test, and verify that the front tyres are free of similar damage. Examine the windscreen wipers for the smearing reported in 2024 and ensure the nail found in the near‑side rear tyre has been removed. A visual check for any rust around suspension mounting points will also help confirm that the underlying structural integrity remains sound.
