2012 Mercedes-Benz SLK 2.1L Diesel · NC12 XCT

The 2012 Mercedes-Benz SLK presents a clean roadworthiness status as of the 5 March 2026 MOT, which the tester passed at 39,652 miles with no defects recorded. The maintenance trend is stable across the five-year record, with every annual test from March 2023 through March 2026 resulting in a pass apart from a single failure two days before the latest pass. That failure on 3 March 2026 at 39,641 miles carried no listed defects, indicating the tester likely rejected the vehicle on a procedural or non-mechanical ground rather than a worn component. The odometer shows 39,652 miles against fourteen years of age, an average of roughly 2,832 miles per year. The SLK has covered only 5,899 miles since the March 2023 test at 33,998 miles, with annual increments of 1,251, 1,496, 2,888, and 11 miles between the two March 2026 entries. Such low yearly use suggests extended standing periods, which on a roadster of this age raises the risk of perished rubber suspension bushes, flat-spotted tyres, and seized brake calipers even though the MOT shows no advisories. A buyer should still commission a physical inspection of the suspension arms and front coil springs, as low-mileage Mercedes of this era commonly develop corrosion at subframe mounts that a pass with no defects will not capture. The brake discs and calipers warrant strip-checking for binding after the long dormancy implied by the mileage. Given the absent advisories and the clean March 2026 result, the vehicle reads as lightly used with basic annual compliance. The unexplained failure two days prior to the pass merits a question to the seller on what was rectified or re-presented, but the record itself shows no worsening mechanical fault.
