MERCEDES-BENZ SLK2013 · 2.1L Diesel

The vehicle’s most recent MOT on 2025-09-26 at 75,659 miles recorded a pass with no defects, indicating stable roadworthiness. Previous tests from 2024-09-25 (71,996 miles) and 2023-09-22 (67,770 miles) also passed without issues, suggesting consistent maintenance. However, the 2024-09-24 test at 71,994 miles recorded a failure despite no defects being listed, raising questions about potential technical errors or unrecorded issues. Overall, the trend shows no emerging mechanical risks, but the unexplained failure warrants scrutiny. The vehicle’s mileage of 75,659 miles over 13 years equates to approximately 5,820 miles annually, significantly below average for its age. This low usage may indicate infrequent driving or prolonged periods of inactivity, which can degrade components like seals, fluids, and electrical systems. Notably, the 2024-09-24 failure occurred just 2 miles after the prior test, suggesting either a data entry anomaly or a rapid deterioration not captured in the records. The absence of recurring defects in other tests implies no systemic wear, but the low mileage pattern necessitates closer inspection of aged parts. A buyer should prioritise checking suspension components, particularly bushes and coil springs, for signs of fatigue or corrosion, as low-mileage vehicles may develop dry rot in rubber elements. The braking system, including calipers and discs, should be examined for binding or uneven wear, as infrequent use can lead to seized components. Structural integrity, especially underbody corrosion, is critical given the potential for moisture ingress during periods of inactivity. While MOT records show no immediate risks, these areas require physical verification to confirm the vehicle’s condition.
