Our Verdict
A potentially strong purchase for a clas
When inspecting this black SL, your primary focus should be on the service history rather than the MOT record alone. While the MOTs from 2023 to 2026 show no defects, an MOT is a minimum safety standard and does not confirm that the complex mechanical and electronic systems of a high-capacity 3.7L Mercedes have been maintained. Ask for evidence of regular oil changes and cooling system maintenance.
Because this is a large-capacity petrol engine, check for any signs of fluid leaks around the engine bay. Given the vehicle's age, you should also negotiate based on the condition of consumables like tyres, brakes, and the battery, as these are not always captured in a 'pass' result unless they cause a failure.
Running this 3724cc petrol engine will involve higher-than-average costs. Expect significant fuel consumption, especially in urban driving, and a higher tax band due to the large engine displacement.
Insurance groups for high-performance Mercedes models tend to be higher, so obtain a quote before committing. Maintenance costs for a vehicle of this age and specification can be substantial, particularly regarding specialized parts for the SL's complex systems. An estimated annual running cost for this vehicle is roughly £2,500-£3,500, depending heavily on annual mileage and insurance profile.
Focus your inspection on the convertible roof mechanism and any electronic controls, as these are critical components not covered by standard MOT inspections. Ensure the roof operates smoothly without hesitation or unusual noises.
Since the MOT history shows no recorded failures for items like suspension or brakes in recent years, you should still perform a physical check of the bushings and tyre tread. Check the engine bay for any signs of weeping gaskets, which is common on older high-displacement Mercedes engines, and verify that all interior electronics are fully functional.
This 2003 Mercedes SL features a large 3.7L petrol engine and has covered 80,288 miles since its first registration in September 2003. The MOT history shows a consistent pattern of passes over the last four years, with no recorded defects or failures between 2023 and 2026. While the MOT records are clean, buyers should remain mindful of the age and engine size of this specific model.
No aggregate MOT data is available for the Mercedes SL to provide a statistical reliability comparison.
