2004 Mercedes-Benz SLK 3.5L Petrol · KC54 APO

The vehicle presents a generally stable maintenance profile, though the most recent MOT on 27 February 2026 at 74,705 miles indicates a shift from the clean records seen in previous years. While the car passed its test, the inspector flagged three specific advisories: a nearside front tyre worn close to the legal limit, a central front oil leak, and a corroded offside rear coil spring. These findings suggest that while the vehicle has been well-maintained in the short term, age-related degradation is beginning to manifest in the suspension and sealing components. The mileage pattern remains exceptionally low for a 2004 model, averaging approximately 3,400 miles per year. The data shows consistent, light usage, with the distance between the July 2024 test at 69,546 miles and the March 2025 test at 71,779 miles representing a typical period of low-intensity driving. However, the jump from 53,076 miles in July 2021 to 59,149 miles in July 2022 shows a slightly higher usage period, which coincided with a failure regarding the steering rack. The overall low mileage supports the idea of a vehicle that has spent significant time stationary, which can sometimes lead to the type of rubber and seal degradation noted in the latest report. A prospective buyer should prioritize a physical inspection of the steering and suspension systems. The 2022 failure involving a missing steering rack gaiter and play in the inner joint suggests the steering assembly has required attention before, so the current condition of the rack and its boots is critical. The recent advisory regarding a corroded offside rear coil spring warrants close scrutiny to ensure the corrosion has not spread to the spring seats or surrounding suspension mounting points. The presence of a central front oil leak in the February 2026 test necessitates a thorough check of the engine seals and oil pan to determine if the leak is a minor seepage or a more significant issue that could lead to fluid loss. Additionally, the recurring mention of tyres worn close to the legal limit, seen in both July 2022 and February 2026, indicates a pattern of deferred consumable replacement. Checking the remaining tread depth and the condition of all four tyres is essential to ensure they meet legal standards and provide adequate grip.
