2004 Mercedes-Benz SLK 2.0L Petrol · EM04 JAN

A recurring pattern of exhaust system issues and lighting aim failures defines the mechanical profile of this vehicle, with the most recent MOT pass on 12 March 2025 showing an ongoing minor leak from the rear exhaust and perishing on the nearside front tyre. The history indicates a persistent issue with the rear exhaust silencer, which has been flagged as an advisory for multiple consecutive years dating back to at least 2021. While the headlamp aim failures recorded in 2021 and 2024 were rectified to achieve subsequent passes, the exhaust leak remains a chronic defect that has not been resolved through the testing cycles. The recorded mileage of 88,009 miles over a 22-year period represents a low annual average of approximately 4,000 miles. This usage pattern suggests the vehicle has spent significant time stationary or has been used only for short, infrequent trips. Mechanically, such low usage can lead to the degradation of rubber components, as evidenced by the advisory for a cracking or perishing nearside front tyre in 2025. It also necessitates closer inspection of seals and fluids that may have aged more than the mileage would typically suggest. Prospective buyers should pay close attention to the exhaust system and the integrity of the braking components. The long-term advisory regarding the rear exhaust leak suggests a weakness in the silencer or its mounting points; during a test drive, listen for any increased engine note, raspiness, or audible blowing sounds, particularly under acceleration. Furthermore, the 2023 advisory regarding corroded rear brake pipes covered in grease requires verification. You should visually inspect the brake lines for signs of heavy corrosion or weeping and check that the brake pedal feel is firm and consistent, without the fluctuations noted in the 2021 record. The condition of the tyres and suspension should also be a priority during physical inspection. Given the advisory for perishing rubber on the nearside front tyre, check all other tyres for sidewall cracking or age-related degradation, even if the tread depth appears sufficient. While no specific suspension failures were recorded, the low annual mileage and the age of the vehicle mean that rubber bushes and mounting components may have hardened. During the test drive, listen for knocks or clunks when traversing uneven surfaces or bumps, which could indicate worn suspension linkages or bushes.
