2013 Mercedes-Benz SLK 2.1L Diesel · KR63 AEN

This Mercedes-Benz SLK from 2013 has maintained a consistent MOT history with no defects recorded across five consecutive tests, most recently passing on 12 November 2025 at 37,777 miles. The absence of advisories or failings suggests the vehicle has been kept in a stable condition, though the most recent test occurred just six months ago—well within the DVSA’s recommended 12-month interval for low-mileage vehicles. No recurring issues have been logged, which implies either diligent maintenance or a vehicle that has not yet exhibited significant wear beyond routine consumables. That said, the lack of advisories does not preclude underlying problems in components like suspension bushes or coil springs, which often degrade gradually without immediate MOT failure. The recorded mileage of 37,777 miles over 13 years equates to approximately 2,906 miles annually, a figure significantly lower than the UK average for this age. There are no abrupt jumps or prolonged gaps in mileage between tests, indicating either consistent light use or extended periods of storage. The most recent mileage increment—1,703 miles between the 2024 and 2025 tests—falls within the expected range for a vehicle of this type. While low mileage generally correlates with reduced wear on high-stress components, it also raises the possibility of deferred maintenance if the car has been left stationary for extended periods, potentially accelerating issues like suspension corrosion or brake fluid degradation. Given the clean MOT record, a buyer should prioritise an in-person inspection of suspension components, particularly the rear coil springs and bushes, which are prone to fatigue in SLK models. The absence of advisories does not rule out subtle wear in these areas, and binding or uneven brake calipers could emerge if the vehicle has been stored without regular use. Examine the brake discs for uneven wear or corrosion, as prolonged inactivity can lead to moisture-related damage. Additionally, check for structural rust around the wheel arches, sills, and subframe, as even low-mileage vehicles can develop hidden corrosion if stored in damp conditions. The engine bay should be inspected for fluid leaks, particularly around the power steering and cooling systems, which are common failure points in this model. Finally, verify the condition of the exhaust system, as catalytic converter efficiency can degrade over time without immediate MOT failure.
