2014 Mercedes-Benz SLK 2.1L Diesel · X666 ADA

The vehicle achieved a PASS on the most recent MOT test dated 21 January 2026 at 72 412 miles with no defects recorded. The immediate preceding test on 20 January 2026 failed, yet the following day the same mileage range produced a PASS, a pattern mirrored in the 2025 cycle. This rapid reversal suggests the maintenance trend is stabilising rather than deteriorating, indicating the car is currently roadworthy and the recent failures did not uncover persistent faults. Mileage accumulation between the recorded MOTs is markedly low. Between January 2024 (68 489 miles) and January 2025 the odometer rose only 1 878 miles, and the increase to January 2026 was 2 025 miles. Over a three‑year span the vehicle added roughly 4 000 miles, which is far below the typical 6 000 miles per year for a 12‑year‑old model. The sparse data set implies periods of limited use or storage, and the annual MOT intervals provide limited insight into any wear that may have occurred between tests. Despite the clean defect logs, the intermittent failures merit a hands‑on inspection. Check the brake discs and pads for uneven wear or glazing, test for binding rear calipers, and assess suspension bushes and coil springs for excessive play. Examine the chassis, convertible top mechanism, and exhaust for corrosion or leaks, and verify tyre tread depth across all four wheels. A thorough review of service records and fluid levels will also help confirm the vehicle’s true condition.
