Our Verdict
A strong recommendation for buyers seeki
Given the very low annual mileage, the primary focus should be on the health of the diesel particulate filter (DPF) and the folding roof mechanism. Ensure the service history shows regular oil changes regardless of the low mileage, as diesel engines can suffer from oil degradation if left idle for long periods.
Verify that the roof operates smoothly and that the seals are intact, as these are common areas of wear for the SLK range. Negotiate based on the age of the tyres and battery, as components can perish over time even if the mileage remains low.
The 2143cc diesel engine offers a balance of performance and efficiency, though tax will be based on the 2015 CO2 emissions brackets. Insurance for a Mercedes-Benz convertible typically falls into a mid-to-high group, which should be factored into the annual budget.
Maintenance costs for the SLK 250 D are generally predictable, but parts for the retractable hard-top can be expensive if repairs are needed. Expect annual costs for fuel, tax, insurance, and basic servicing to be moderate for a premium vehicle.
While the MOT history shows no defects, you should manually test the operation of the retractable hard-top to ensure there are no hesitations or leaks. Inspect the brake discs for surface corrosion, which can occur on vehicles with very low annual usage.
Check for any signs of soot buildup or warning lights related to the DPF, as the recorded average of approximately 2,900 miles per year may not have been sufficient to keep the filter clear. Finally, inspect the red paintwork for any fading or stone chips that would not be captured in an MOT test.
This red 2015 Mercedes-Benz SLK 250 D has covered 31,817 miles as of its most recent test in July 2026. The vehicle's MOT history is exceptionally clean, recording five consecutive passes with no defects or advisories listed between 2022 and 2026. It represents a low-mileage option compared to typical usage patterns for this model.
The SLK 250 D shows a respectable average MOT pass rate of 86.4% across the analysed sample.
