2004 Mercedes-Benz SLK 3.5L Petrol · M5 PDX

The vehicle currently holds a roadworthy status, but the record reveals a history of significant structural and mechanical neglect. While it passed the most recent test in June 2024 at 105,056 miles, this followed a critical failure in June 2023. The maintenance trend shows a pattern of reactive repairs where major safety defects are only addressed after failing, rather than through proactive preventative maintenance. The structural integrity of the rear section remains the primary concern for this specific model. At 22 years old, the recorded mileage of 105,056 miles is notably low, averaging approximately 4,800 miles per year. However, the data shows a period of inactivity between June 2023 and June 2024, where the car covered only 400 miles in twelve months. Such low annual usage often correlates with the degradation of rubber-based components, which is evidenced by the 2023 report of perishing front tyres and the persistent issue of brake pipe corrosion despite the low distance traveled on the vehicle. A buyer must conduct a thorough physical inspection of the rear subframe, as the 2023 failure flagged this component as seriously corroded and weakened. Although the record indicates it was covered with underseal post-failure, this treatment often masks ongoing rust progression rather than curing it. The suspension also requires close scrutiny; the history notes a fractured offside front coil spring and play in the anti-roll bar linkage, suggesting that components are reaching the end of life. The braking system indicates a consistent failure to monitor basic consumable items. The vehicle failed in 2022 for dangerously thin brake pads and corroded pipes, and the 2024 test found both rear tyres at the legal wear limit. The presence of high carbon monoxide readings in 2022 also suggests potential engine management issues or catalytic converter inefficiency that were never fully resolved. Inspection of all brake lines and the exhaust system is essential to ensure the previously noted corrosion has not returned.
