2015 Mercedes-Benz SLK 2.1L Diesel · ST04 JWT

The overall roadworthiness status reflects a stable maintenance trend, anchored by the May 2, 2025 test at an unspecified mileage where the vehicle passed with zero defects recorded. This clean outcome matches the preceding three annual tests from April 2023, April 2024, and January 2022, all of which also resulted in straight passes without any advisories or failures noted on the certificates. A single test on January 28, 2022 recorded an initial failure alongside a pass on the same day, though specific failure reasons were omitted from the dataset. The vehicle accumulates mileage at a rate roughly typical for its age, sitting at 113,600 recorded miles across its roughly eleven-year lifespan. This equates to an average of approximately 10,300 miles per year. The testing cadence shows consistent annual presentations between January 2022 and May 2025, indicating regular use and ongoing statutory testing without extended periods of SORN or abandonment. The notable absence of recurring advisory items across four consecutive pass certificates means the history provides very little raw data regarding wear on consumables. A physical inspection must therefore focus heavily on high-wear mechanical systems that evade detection during a basic MOT test. Check the condition of the brake discs and pads, as high-mileage Mercedes-Benz models frequently require friction component replacement. Inspect the multi-link suspension bushes, dampers, and coil springs for play or degradation, alongside checking the operation of the retractable hardtop mechanism for binding or electrical faults. Verify the subframes and structural chassis members for surface corrosion, paying close attention to areas vulnerable to road salt accumulation.
