Our Verdict
A recommended purchase based on its cons
Verify that the rear brake discs mentioned in the November 2024 MOT were replaced or refurbished. Ensure the service history reflects regular oil changes for the 2143cc diesel engine to maintain longevity. Given the vehicle's age, it is also advisable to check for any leaks or wear around the convertible roof seals.
When negotiating, consider that while the MOT history is clean, the mileage is higher than the average for this model. Use this as a point of discussion regarding the remaining life of wear-and-tear components like the battery and tyres.
The 2.1L diesel engine typically offers better fuel economy than the petrol variants, though road tax and insurance will be reflective of the SLK's premium positioning. Maintenance costs for Mercedes-Benz are generally higher than average, particularly for specialized parts and specialist labour.
Annual costs will be comprised of diesel fuel, the applicable tax band for a 2012 diesel, and insurance. Regular servicing for a diesel of this age is essential to avoid expensive DPF or fuel system issues.
Pay close attention to the rear braking system, as the 2024 MOT specifically noted pitted and scored discs. Check the suspension arms for wear or play, as these are identified as a common failure point across the wider SLK range in aggregate MOT data.
Additionally, operate the folding roof mechanism several times to ensure it opens and closes smoothly without hesitation. Check the silver paintwork for any signs of clear-coat failure or corrosion, which can occur on vehicles of this vintage.
This 2012 diesel SLK has recorded 91,443 miles and shows a stable MOT history. Between 2021 and 2025, it passed every test, with only a single advisory for worn rear brake discs in 2024. It presents as a consistent example of the model with a clear testing trail.
The SLK has an average MOT pass rate of 81.2%, with common failures frequently linked to suspension arms and braking components.
