2007 Mercedes-Benz SLK 1.8L Petrol · KP57 ACZ

The vehicle is currently roadworthy, but the maintenance history reveals a worsening trend regarding structural degradation and mechanical neglect. While it passed its most recent test in February 2026 at 113,539 miles, this followed a significant failure just eleven days prior. That failure highlighted a critical structural issue where the nearside rear sub-frame was corroded and seriously weakened, alongside a fractured offside front coil spring and corroded rear brake pipes. The fact that the structural integrity of the chassis has reached a point of failure suggests deep-seated rust issues. The mileage profile is notably low for a 19-year-old vehicle, averaging approximately 6,000 miles per year. However, the data suggests long periods of inactivity or infrequent use, which has contributed to specific issues. For instance, the car covered only 4,526 miles between January 2024 and January 2025, and another 5,408 miles the following year. This low mileage is consistent with the recurring reports of perished or cracking tyres and deteriorated rubber mounts, indicating that rubber components are failing due to age and exposure rather than simply from wear. A buyer must conduct a thorough physical inspection of the underside to verify the quality of the sub-frame repairs. The record moved from "corroded" in 2023 to "seriously weakened" by early 2026, implying the corrosion is active and aggressive. Close attention should also be paid to the rear brake lines, which have been flagged for corrosion across multiple years of testing. Furthermore, the recurring history of worn suspension arm bushes and fractured springs suggests that the suspension geometry is nearing the end of its functional life and may require significant investment to maintain vehicle handling and safety.
