2004 Mercedes SL 3.7L Petrol · LL04 YMZ

The 2004 Mercedes SL is currently roadworthy, with the most recent MOT on 2026-05-22 confirming compliance at 92,211 miles. However, recurring minor issues suggest a maintenance trend leaning toward stability rather than improvement. The latest test identified brake hose corrosion and a corroded brake pipe, both classified as advisory items. Earlier records show consistent suspension and wheel bearing play, with no major structural or emission failures. While the vehicle has passed all tests, the persistence of minor faults indicates potential for gradual wear in critical areas like braking and suspension systems. The mileage of 92,211 miles over 22 years equates to approximately 4,191 miles annually, significantly lower than average for a vehicle of this age. This suggests infrequent use or periods of inactivity, which can accelerate corrosion in components like brake pipes and suspension bushes. The MOT history shows annual testing with minimal gaps, but the low mileage raises concerns about underused systems. For instance, the 2023 test noted deteriorating front wipers and wheel bearing play, while the 2022 test flagged multiple suspension and wheel bearing issues. These patterns imply that the vehicle may require closer scrutiny of components prone to stagnation or delayed wear. A buyer should prioritise inspecting the suspension system, particularly the front wheel bearings and upper suspension arm ball joints, which showed recurring play. The brake system requires attention, given the 2026 corrosion findings and earlier reports of binding calipers and uneven parking brake effort. Additionally, the low mileage may have left the exhaust and corrosion-prone components in a state of disuse, necessitating a thorough check for rust or leaks. The absence of major structural defects in the MOT history is reassuring, but the vehicle’s age and usage pattern demand a detailed mechanical inspection to confirm the integrity of its core systems.
