2004 Mercedes-Benz SLK 3.5L Petrol · LM54 ABZ

The vehicle most recently passed its MOT on 14 June 2025 with no defects recorded. Reviewing the history back to 2022, the maintenance trend is exceptionally stable, with four consecutive clean passes and a total absence of advisories. This suggests a vehicle that has been meticulously maintained or has benefited from proactive preventative care, as it is uncommon for a vehicle of this vintage to present without any noted wear on consumables or suspension components. With a recorded mileage of 88,390 miles over a 22-year period, the car has averaged approximately 4,018 miles per year. This is considerably lower than typical usage patterns, indicating the vehicle has likely been used as a seasonal or secondary car. While this results in less mechanical wear on the engine and drivetrain, low-usage vehicles are often susceptible to issues stemming from prolonged inactivity, such as the perishing of rubber seals and the degradation of fluids. Given the clean MOT record and low mileage, the buyer should focus on age-related deterioration rather than wear-and-tear. It is essential to inspect the tyre sidewalls for cracking or perishing, as tyres often reach their age limit before their tread limit. The braking system should be checked for binding calipers or heavy surface corrosion on the discs, which can occur when a vehicle stands for extended periods. During a test drive, listen for any knocks or clunks from the suspension bushes and coil springs, as these rubber components can harden and lose elasticity over two decades regardless of the mileage covered. Further attention should be directed toward the 12V battery health and the condition of the engine oil and coolant, as these degrade based on time rather than distance. The service history should be verified to ensure that fluid changes have been performed on a calendar basis. For this specific model, the operation of the retractable hardtop must be thoroughly tested for smooth movement and seal integrity to prevent water ingress. Finally, a physical inspection of the underbody, specifically the sills and wheel arches, is advised to ensure that no structural corrosion has developed during periods of storage.
