2020 Mercedes-Benz C 220 Sport Edition Prem + D A 1.9L Diesel · YC70 NAO

A pattern of recurring advisory items points toward a chassis and underbody that is now beginning to show typical mid-life wear, despite the vehicle having passed every recorded DVSA test without a single failure. The most recent examination on 19 November 2025 returned a pass with an advisory for wear at the offside front lower suspension arm pin or bush, specifically the shock bush, while the preceding test on 9 October 2025 flagged a minor exhaust gas leak together with edge wear on all four tyres. Taken together with the 2023 entry, where all four tyres were again recorded at the legal limit, the trajectory is one of steady, predictable component consumption rather than any sudden deterioration. There are no advisories relating to brake discs, pads, lines, corrosion of structural items, or fluid leaks, which keeps the overall roadworthiness picture reassuringly stable. Mileage stands at 50,077 miles over six years, equating to an annual accumulation of roughly 8,346 miles. This figure sits squarely within the expected band for a privately owned executive saloon and indicates regular but not exhaustive use. The testing history shows a small anomaly worth flagging: two tests were carried out in quick succession in late 2025, with the most recent pass following the October examination by only six weeks, suggesting the vehicle may have been returned shortly after a minor exhaust or tyre issue was addressed. There are no extended lay-up periods that would raise concerns about seized calipers, perished rubber, or stale fluids, so the usage pattern supports the view that mechanical components have been worked consistently rather than allowed to deteriorate through standing. For a prospective buyer, the priority on inspection should be the front suspension, given the recorded bush wear. On a test drive, listen for any clonking or knocking from the front end over speed humps, cats-eyes, and uneven road surfaces, particularly under braking or when steering from lock to lock. Pay close attention to vague or wandering steering response, as worn lower arm bushes can allow the wheel to subtly shift geometry under load. A handheld check beneath the car on a ramp would be wise to confirm whether the offside front lower arm bush has worsened since November 2025, as bushes flagged at MOT tend to progress once identified. Also inspect the nearside and offside rear bushes for similar deterioration, since the component wear seen at the front often appears at the rear within a similar timeframe on this generation of C-Class. The exhaust system warrants a thorough visual and auditory check as well. With a minor leak already noted in October 2025, listen at idle for any change in exhaust note, a hissing or ticking sound from the engine bay, or any smell of exhaust gases inside the cabin, particularly with the rear screen open. Examine the joint between the engine and the front pipe, the flex section, and the rear silencer mounting rubbers, as Mercedes-Benz W205 exhaust systems are known to develop corrosion at the front flexible joint. Tyre wear has been flagged at every test since 2023 and on a four-wheel basis, so a prospective buyer should examine the current set for uneven shoulder wear, which can indicate alignment geometry issues rather than simply ageing rubber. A four-wheel alignment check and a fresh set of premium tyres should be factored into any offer, alongside a quotation for the front suspension bush replacement if movement is now measurable.
