2013 Mercedes-Benz SLK 2.1L Diesel · WV63 YCU

The vehicle’s recent MOT history indicates a deteriorating maintenance trend rather than stable or improving condition. The May 2025 test passed without defects at 86,117 miles, yet this follows a failure in April 2025 at 86,093 miles where the Nearside Front Shock absorbers exhibited a serious fluid leak and the Nearside Front Anti-roll bar ball joint was excessively worn. Prior to this, the car failed its MOT in April 2024 due to fractured coil springs and excessive wear on both front suspension ball joints, with the latter test recording 83,353 miles. These recurring front-end suspension failures, spaced less than a year apart, suggest accelerated component degradation requiring urgent attention. Mileage progression aligns with the vehicle’s age, accumulating approximately 6,624 miles annually over its 13-year lifespan. The record shows consistent annual testing from 2016 onwards, with mileage rising steadily from 35,553 miles in April 2016 to 86,117 miles in May 2025. A notable irregularity occurred in September 2020, where the car failed its MOT just five miles after passing it the same day, flagging exposed tyre ply, brake disc corrosion, and tyre wear. This dual-test anomaly highlights potential deferred maintenance or a sudden mechanical failure during that period. Prospective buyers should prioritise a thorough inspection of the front suspension system, focusing on the condition of shock absorbers, anti-roll bar ball joints, coil springs, and suspension arms. The repeated failures in these areas, particularly the 2024 coil spring fractures and 2025 shock absorber leaks, raise concerns about structural integrity and alignment. The brake system also warrants scrutiny, given the 2020 rear brake disc corrosion and the 2019 and 2018 records noting thin brake pads and fluctuating brake performance. Additionally, the 2020 tyre failures and 2017 Nearside Rear Tyre wear approaching legal limits suggest checking tyre condition and tread depth across all wheels. Any signs of fluid leaks under the vehicle or unusual noises during cornering or braking would further validate the need for immediate mechanical intervention.
