Our Verdict
A strong candidate for a modern classic.
Focus on verifying the service history to ensure the 3.7L engine has been maintained despite the low annual mileage. Check for evidence of any mechanical work performed around the February 2026 MOT failure, as the records show a failure followed by a pass shortly after. Ensure all electronic components and the convertible roof mechanism operate smoothly, as these are critical on a vehicle of this age.
With a 3724cc petrol engine, fuel consumption will be significant, and it will fall into a higher CO2 tax bracket. Insurance for a high-capacity luxury convertible is typically higher, and maintenance for a Mercedes of this era can be costly due to parts and labour specialisation.
Annual costs will be driven primarily by fuel and insurance, with a need for a dedicated budget for preventative maintenance to keep the vehicle roadworthy.
Inspect the vehicle for any signs of corrosion, particularly around the wheel arches and sills, though no such issues are noted in the MOT history. Pay close attention to the tyres and brakes, as low-mileage cars can suffer from perishing rubber or seized calipers.
Review the specific reason for the February 2026 MOT failure, as the provided data lists it as a failure without specifying the defect. This should be clarified with the seller to ensure the issue was fully resolved before the subsequent pass on March 6th.
This 2004 Mercedes SL 350 has covered 107,973 miles over 22 years, indicating relatively low annual usage. The MOT history shows four passes and one failure since 2022, with no defects recorded on the most recent test in March 2026. Its silver exterior and 3.7L petrol engine represent a classic luxury specification.
No aggregate reliability data is available for this specific model variant.
