2012 Mercedes-Benz SLK 2.1L Diesel · RO58 BOB

The vehicle passed its most recent MOT on 21 August 2026 with no defects recorded. The overall maintenance trend appears stable, although the history reveals a significant failure in August 2025 concerning excessively corroded rear brake pipes on both the nearside and offside. The prompt rectification of these faults and the subsequent clean pass in 2026 suggest that the vehicle is currently maintained to a roadworthy standard and that the owner is responsive to critical safety failures. With a recorded mileage of 109,833 miles over approximately 14 years, the vehicle has averaged roughly 7,845 miles per year. This is considered typical usage for its age, indicating a consistent history of use rather than long periods of standing or excessive high-mileage wear. From a mechanical perspective, this level of usage suggests that while the engine and drivetrain should be well-seasoned, the vehicle is now at a stage where rubber components, suspension bushings, and engine mounts may be nearing the end of their natural service life. The previous failure regarding corroded brake pipes is a critical point for inspection. Corrosion in brake lines is often a symptom of exposure to road salt and moisture, and while the failed sections were replaced to pass the MOT, it is essential to verify the condition of the remaining lines. A prospective buyer should inspect all exposed metal brake piping for surface rust or bubbling. During the test drive, pay close attention to the brake pedal feel; any sponginess or a lack of firm resistance could indicate further degradation or air within the hydraulic system. Beyond the brake system, the buyer should conduct several age-related physical checks. Inspect the tyre sidewalls for perishing or fine cracking, as rubber degrades over time even if the tread remains legal. Verify the service records for calendar-based fluid changes, specifically the automatic transmission fluid and coolant, which degrade chemically regardless of mileage. Finally, check for any binding calipers or uneven corrosion on the brake discs, and ensure the 12V battery is healthy, as voltage fluctuations in these models can adversely affect the electronic operation of the folding roof mechanism.
