MERCEDES SLK2006 · 3.0L PETROL

The vehicle is currently roadworthy, but the maintenance trend indicates a concerning shift toward structural and suspension degradation. While it passed the most recent test in November 2025 at 125,864 miles, the tester identified a corroded offside rear coil spring. This follows a more significant failure in November 2024 where the nearside rear subframe was flagged as seriously weakened by corrosion. The progression from minor ball joint wear to structural weakening suggests the vehicle is suffering from active oxidation. At 125,864 miles over 20 years, the SLK averages approximately 6,300 miles per year, which aligns with typical light usage for a luxury roadster. The record shows consistent annual testing, with roughly 4,700 miles driven between the 2023 and 2024 tests, and another 4,400 miles prior to the 2025 inspection. This steady mileage suggests the car has not sat stationary for long periods, which often exacerbates the deterioration of rubber components and brake surfaces. A buyer must conduct a thorough physical inspection of the subframe to ensure the structural corrosion noted in 2024 has been properly addressed rather than merely masked. A seriously weakened subframe is a critical safety concern that often requires professional welding or component replacement. Additionally, the front suspension arms, bushes, and ball joints should be inspected closely, as these were recurring points of failure across the 2023 and 2024 records. The presence of a corroded coil spring in the latest report further confirms that underbody components are reaching the end of their functional life due to age and environment.
