2014 Mercedes-Benz SLK 2.1L Diesel · WL64 GHD

The 2014 Mercedes-Benz SLK presents a clean MOT record with a stable and consistently improving maintenance trend. The most recent test on 12 September 2025 at 67,525 miles passed with zero defects, marking three consecutive flawless MOTs since 2023. The single advisory cluster in 2024 has been resolved, suggesting the previous owner addressed tyre wear promptly rather than letting it recur. The mileage profile tells a clear story of low, steady use. Over roughly twelve years, the car has covered 67,525 miles, averaging approximately 5,627 miles annually. The MOT records confirm consistent yearly mileage accumulation: 46,170 miles in August 2021, 52,446 in September 2022, 57,643 in September 2023, 63,186 in September 2024, and 67,525 in September 2025. Each year shows a gain of roughly 5,000 to 5,500 miles, indicating regular use without long periods of inactivity or sudden high-mileage bursts. No gaps appear in the annual testing pattern, which supports the reliability of this odometer record. Despite the clean MOT history, a buyer should still inspect the underside for corrosion, particularly around suspension mounting points, sills, and subframes, as these structural areas are not always fully visible during an MOT but degrade over time on older Mercedes models. The 2024 advisories on both rear tyres wearing on their edges suggest possible misalignment or worn suspension bushes, so checking the condition of rear trailing arm bushes, anti-roll bar links, and wheel alignment settings is worthwhile. Brake discs and pads should be examined for uneven wear, and the exhaust system inspected for corrosion, especially around the rear silencer. The folding hardtop mechanism on the SLK deserves particular attention, including hydraulic rams, roof seals, and alignment, as these are known weak points that MOTs do not fully stress-test under normal conditions.
