2007 Mercedes-Benz SLK 3.0L Petrol · B1 WFT

The most recent MOT (5 Sept 2025) was passed at 54,133 mi, but it flagged three serious items: rear brake pads close to the limit, a corroded rear brake pipe and general corrosion on rear suspension components. A recurring pattern emerges around the rear of the car. In 2021 the MOT noted slight play in both front‑lower and rear suspension arm ball joints, and by 2025 the rear suspension is described as corroded. The brake system also shows wear, with thin pads and a rust‑affected pipe. This suggests a gradual decline rather than a sudden failure, but the defects are becoming more pronounced. Mileage is very low for a 2007 model – about 2,850 mi per year. Low usage can mean less overall wear on drivetrain and engine parts, but it also often correlates with long periods of inactivity, which encourages rust on brake lines and suspension brackets. The mileage alone does not guarantee good condition; the emerging corrosion points to possible under‑use effects. Overall the trend is moving from clean MOTs (2022‑2024) to emerging wear and rust in 2025. The vehicle is not showing a rapid deterioration, but the rear brake and suspension issues should be taken seriously.
