2009 Mercedes-Benz SLK 3.0L Petrol · HR09 SLK

The vehicle presents a stable roadworthiness status with a clear trend of improvement following a period of mechanical concern. The most recent test in September 2025 at 38,690 miles recorded no defects, indicating that the various mechanical issues identified in previous years have been addressed. This follows a clean result in 2024, suggesting the current ownership is actively maintaining the car after the series of failures seen earlier in the history. The mileage profile is exceptionally low for a 17-year-old vehicle, averaging approximately 2,276 miles per year. The data shows consistent, low-intensity usage, for example, only 1,365 miles accumulated between September 2024 and 2025. While this low mileage reduces wear on the drivetrain, it directly explains the recurring age-related degradation of rubber components, which were flagged across multiple tests between 2021 and 2023 due to perishing and cracking of tyres due to time rather than tread wear. A buyer should focus physical inspection on the front suspension, as the history shows recurring faults in this area. The 2023 test at 35,693 miles flagged worn suspension arm bushes and a nearside front wheel bearing with play, following a fractured coil spring failure in the previous year. Although these appear to have been rectified, the low-mileage nature often means rubber bushes can dry out and crack prematurely. You should check for any signs of fresh movement or play in the steering geometry. The braking system also warrants attention due to past reports of low parking brake performance in 2018 and worn front brake discs in 2023. Given the car's low usage, there is a risk of calipers seizing or discs rusting from sitting, so you must check for corrosion on the rotors and brake fluid degradation. The 2021 failure regarding high carbon monoxide and the engine management light suggests the engine management system previously required intervention, though the recent clean records indicate these systems are now functioning within parameters.
