2012 Mercedes-Benz SLK 2.1L Diesel · D1 OLM

The 2012 Mercedes-Benz SLK presents a clean roadworthiness status with a stable maintenance trend. The most recent test on 8 November 2025 at 59,850 miles returned a pass with no defects recorded, continuing an unbroken sequence of annual passes since at least November 2021. The vehicle shows no advisories or mechanical faults across the entire supplied record, indicating consistent compliance with statutory test standards. Annual mileage sits well below typical use for a 14-year-old car. The record shows 36,926 miles in November 2021, rising to 44,852 by November 2022, then 49,464 in November 2023, 54,374 in November 2024, and 59,850 in November 2025. That equates to roughly 4,275 miles per year overall, with the largest single-year movement being 7,926 miles between 2021 and 2022. The clean test history with no flagged wear items suggests the previous keeper maintained the car to a reasonable standard and avoided deferred consumable replacement. Given the absence of any recorded advisories on tyres, brakes, suspension bushes, coil springs, exhaust emissions, or structural corrosion, the MOT data alone reveals no recurring fault patterns requiring caution. A buyer should still commission a physical inspection to verify underbody condition and check for latent corrosion around subframes and suspension mounts, as MOT passes do not certify absence of developing rust. Low annual use over long intervals can allow brake calipers to seize or fluids to degrade without triggering test failures. The SLK's retractable roof mechanism and hydraulic lines warrant hands-on verification despite the spotless paper record.
