2013 Mercedes-Benz SLK 2.1L Diesel · P30 DBP

A consistent run of clean MOT passes defines this 2013 Mercedes-Benz SLK, with the most recent test on 26 February 2026 recording no defects and no advisories, continuing an unbroken sequence of pass-with-no-defect outcomes stretching back through the 2025, 2024, 2023 and 2022 tests. Across a five-year MOT window the vehicle has not produced a single advisory, which is unusual for a car now in its thirteenth year and indicates that the wear-related items typically flagged on older vehicles, such as brake component condition, suspension bush wear, exhaust integrity and corrosion, have not yet reached the threshold for tester comment. This pattern suggests the car has either been maintained to a high standard with proactive replacement of consumables or has seen genuinely light use that has not pushed components to advisory thresholds. From a roadworthiness perspective the recorded test history is reassuringly stable, with no deterioration trend to track and no components currently flagged as approaching failure. The recorded mileage of 74,747 miles against a 2013 registration equates to an annual accumulation of roughly 5,750 miles, which is well below the average for a vehicle of this age and points to either genuine low-mileage use or extended periods of inactivity. There are no notable gaps between test dates in the MOT history, but the mileage progression between consecutive tests should be reviewed in person via the V5C and service records to confirm the usage pattern; a low annual mileage figure is mechanically significant because it reduces wear on major drivetrain and suspension components but can introduce issues associated with stationary periods, including corrosion on brake discs, deterioration of rubber seals and bushes, and moisture accumulation in fluids. Confirming whether the car has been used regularly on longer runs rather than purely short trips is important, as short-trip use without sufficient warm-up can leave oil and coolant systems vulnerable to contamination and accelerated degradation. For a prospective buyer, the absence of recorded advisories means the usual MOT-driven shortlist of components to scrutinise on inspection is not available, so attention should shift to age and mileage-related items that testers typically only flag once wear is advanced. On a test drive, listen for any knocking or creaking from the front suspension over bumps, particularly from the lower control arm bushes and anti-roll bar links, and feel for vagueness or looseness through the steering that could indicate worn tie rod ends or top mounts. With brake components, expect to see surface corrosion on the discs if the car has been standing, which should clear under braking, but persistent judder or vibration under pedal pressure would suggest lipping or disc run-out requiring machining or replacement. Visually inspect the underside for any early signs of corrosion on subframe components, brake pipe runs and exhaust mounting points, particularly given the age of the vehicle. Finally, given the confirmed low-mileage profile, it is sensible to check the condition of all under-bonnet and undercarriage rubber items including drive shaft boots, steering rack gaiters and suspension dust covers, as these deteriorate with age rather than mileage and can fail roadworthiness criteria once split. Verify the state of all fluid services by date and mileage stamps in the service book, particularly engine oil, brake fluid, coolant and the automatic transmission fluid where applicable, as long gaps between changes on a low-mileage car are common and may need addressing regardless of MOT status. Road test the convertible roof mechanism thoroughly if the vehicle is a folding hard-top variant, ensuring it completes a full cycle without hesitation, unusual noises or warning messages, as this system is complex and repairs are costly. Confirm that the supplementary restraint system warning lamps extinguish promptly after ignition, as airbag and seatbelt pretensioner faults are common faults on SLK models of this era and would not necessarily appear in the MOT record.
