2012 Mercedes-Benz SLK 1.8L Petrol · NX12 OVF

The most recent DVSA MOT test on 5 February 2026 recorded a pass at 46,890 miles with no defects noted, confirming the vehicle remains roadworthy at this time. The maintenance trend is clearly stable across the available record: the SLK passed its two prior tests on 18 July 2024 and 13 June 2023 without advisories or failures. No recurring faults appear in the history, and no consumable items have been flagged for replacement. The vehicle has maintained a clean MOT record over approximately two and a half years of testing. The mileage data reveals an extremely low annual usage pattern consistent with the vehicle's age. Over the full 14-year lifespan, the car has averaged roughly 3,349 miles per year, which is well below typical UK usage. More notably, the mileage accumulation has slowed dramatically in recent years: only 132 miles separated the June 2023 and July 2024 tests, and just 56 miles were added between July 2024 and February 2026. This suggests the SLK may have spent extended periods stationary, which raises specific concerns about rubber components, seals, fuel system integrity, and brake corrosion from disuse rather than wear. Despite the clean MOT record, a buyer should conduct thorough in-person inspections focusing on areas not fully assessed by standard MOT testing. The brake discs and calipers warrant close examination for surface corrosion or seized components, as prolonged standing accelerates rust formation on ferrous brake components even without driving. The fabric or leather interior should be checked for mould, damp ingress, and perished rubber seals around the hood mechanism, given the SLK's folding roof design. The engine bay and undercarriage deserve attention for fluid leaks, degraded rubber hoses, and corrosion on suspension components that may have seized from disuse. Tyre condition must be verified, including the spare if fitted, as rubber compounds deteriorate with age regardless of mileage. A compression test or oil analysis would provide additional assurance regarding engine health after such limited use.
