2001 Mercedes-Benz SLK 3.2L Petrol · LR51 YFA

The vehicle’s most recent MOT test on 2024-08-30 confirms it remains roadworthy, though the preceding failure on 2024-08-29—just a day earlier—demonstrates a narrow escape from minor but avoidable issues. The failure was driven by two non-structural faults: a non-functioning front windscreen washer and an out-of-specification exhaust Lambda reading, both of which are correctable with basic servicing. The absence of any major defects in the 2023 and 2022 tests suggests these were isolated oversights rather than a worsening trend. However, the Lambda sensor failure hints at either a neglected emissions system or a recurring calibration issue, which should be verified during an in-person inspection. The recorded mileage of 132,124 miles over 25 years equates to approximately 5,285 miles annually, a figure significantly lower than the average for a vehicle of this age. The consistent annual mileage increments—rising by around 400–500 miles each year—indicate steady, albeit light, usage without abrupt spikes or prolonged periods of inactivity. There are no gaps in the MOT history that would suggest extended neglect, though the low mileage does imply reduced wear on high-mileage components like suspension bushes or drivetrain seals. Still, the lack of pre-MOT servicing records means potential hidden wear cannot be ruled out. Given the MOT history, a buyer should prioritise an inspection of the exhaust system, particularly the Lambda sensor and associated wiring, to confirm whether the 2024 failure was a one-off or part of a broader emissions issue. The front windscreen washer failure suggests basic fluid maintenance may have been overlooked, so checking for other consumables—such as brake fluid, power steering fluid, and coolant levels—would be prudent. Given the vehicle’s age, the suspension components, including coil springs, bushes, and shock absorbers, should be examined for wear or corrosion, as should the brake calipers and discs for uneven wear or binding. Structural integrity, particularly around the wheel arches and sills, should also be assessed for rust or damage, given the SLK’s roadster construction.
