2015 Mercedes-Benz SLK 2.1L Diesel · WF15 DWN

The 2015 Mercedes-Benz SLK presents a stable roadworthiness status with a clean pass recorded at the most recent test on 3 February 2026 at 38,398 miles. The maintenance trend shows no worsening defects across the five-year MOT span. The February 2026 pass followed an earlier clean pass on 18 February 2025 at 36,838 miles, and the only blemish was a failed test on 15 February 2025 at the same mileage with no defects logged, indicating an administrative or presentation error rather than a mechanical fault. Mileage remains low for an eleven-year-old vehicle, totalling 38,398 miles or roughly 3,491 miles per year. The record shows gentle annual accumulation: 30,196 miles in February 2023, 34,260 in February 2024, 36,838 in February 2025, and 38,398 by February 2026. No rapid jumps or standing gaps appear. The clean history with zero advisories across every test suggests the previous owner kept basic consumables and structural items within limits, though low use can mask degraded rubber bushes or corroding brake discs from disuse. A buyer should still commission a physical inspection of suspension bushes, coil springs, and brake calipers for binding or seizing, as low-mileage SLK models often develop such faults through prolonged inactivity rather than wear. The absence of recorded corrosion or exhaust advisories is reassuring, but DVSA testers do not strip components. Verify underside structural integrity and tyre sidewall condition where the car may have rested on flat spots during storage.
