2013 Mercedes-Benz SLK 2.1L Diesel · KM13 BKK

The most recent MOT test on 13 May 2026 resulted in a pass with no recorded defects. When evaluating the long-term maintenance trend, the vehicle shows signs of reactive repair following a period of component degradation. A significant failure occurred in January 2025 involving a major fluid leak from the nearside front shock absorber and an excessively worn nearside front suspension arm bush. This followed a previous advisory for the same bush in 2022, indicating that the wear was monitored before being rectified. The subsequent passes in 2025 and 2026 suggest that these critical suspension issues have been addressed, moving the vehicle from a period of worsening condition back into a stable maintenance profile. With 99,072 miles recorded over 13 years, the vehicle averages approximately 7,621 miles per year. This represents typical, moderate usage for a premium roadster and suggests the car has been driven regularly rather than left to sit for long durations. While the mileage is not exceptionally low, it is well within the expected range for its age, meaning the mechanical components have been subject to standard wear cycles. The steady accumulation of mileage implies that the vehicle is likely to have a more consistent mechanical history than a car that has suffered from long periods of inactivity, which can often lead to seized calipers or perished rubber components. During your inspection and test drive, you must pay close attention to the front suspension to ensure the recent repairs were effective. Listen for any dull thuds, clunks, or metallic knocking sounds when driving over speed bumps or uneven road surfaces, as these are primary indicators of failing suspension bushes or dampers. You should also visually inspect the nearside front shock absorber for any signs of fresh oil weeping, which would indicate a faulty replacement or a recurring leak. Furthermore, inspect the tyre condition carefully; the 2021 advisory regarding perishing and uneven inner edge wear suggests a history of alignment or age-related rubber degradation. Check all tyres for sidewall cracking and ensure the tread wear is even across the width of the tyre to rule out ongoing suspension or geometry issues. Beyond the recorded suspension history, a vehicle of this age requires a thorough check of time-sensitive consumables. Verify through the service book that brake fluid and engine coolant have been changed according to manufacturer intervals, as these fluids absorb moisture and degrade over time regardless of mileage. Given the vehicle's profile, check the 12V battery health and inspect the convertible roof mechanism for smooth operation and any signs of hydraulic leaks. Finally, examine the brake discs for excessive corrosion or scoring, and ensure there is no sign of binding calipers, which can occur if the vehicle has experienced periods of standing.
