2015 Mercedes-Benz SLK 2.1L Diesel · MX65 VVS

The Mercedes-Benz SLK has maintained an exceptionally clean MOT history over the past three years, with the most recent test on 22 August 2025 at 69,279 miles showing no defects or advisories. This consistency extends back to August 2022, where the only anomaly was a failed test on 18 August 2022 at 56,068 miles—an isolated incident with no recorded faults, suggesting a possible administrative error rather than a mechanical issue. The absence of recurring advisories or failures indicates stable maintenance, with no signs of worsening wear in critical areas like brakes, suspension, or structural integrity. The vehicle’s compliance across four consecutive tests, including the most recent one just ten months ago, aligns with a well-kept example for its age. The SLK’s mileage accumulation of 6,298 miles per year is broadly in line with its 11-year lifespan, reflecting either moderate use or periodic storage. There are no abrupt spikes or prolonged gaps in the record; mileage increased steadily from 56,069 miles in August 2022 to 69,279 miles in August 2025, suggesting consistent but not excessive driving habits. The lack of mileage-related wear advisories in any test further supports the idea that the vehicle has been maintained according to manufacturer recommendations, avoiding the kind of rapid degradation often seen in high-mileage or neglected examples. For a prospective buyer, the primary focus should be on components not routinely checked during MOTs, such as the convertible top mechanism, hydraulic fluid condition, and the integrity of the soft-top boot if fitted. Given the absence of brake-related advisories, a closer inspection of the rear brake calipers—commonly prone to binding in SLK models—would be prudent, alongside checking for any signs of corrosion in the wheel arches or underbody, particularly around the exhaust and suspension mounts. The suspension bushes and coil springs, though not flagged here, should be assessed for wear or leaks, as these are high-stress areas in a convertible with frequent top deployment. The clean MOT history reduces immediate concerns, but a pre-purchase inspection by a Mercedes specialist would be advisable to confirm the absence of hidden wear in less frequently tested systems.
