Our Verdict
Proceed with extreme caution regarding this 2004 Mercedes-Benz SL. While the low mileage is attractive, the complete lack of MOT history since February 2020 suggests the vehicle has been off the road for over six years, which poses significant mechanical and electrical risks.
Before committing to a purchase, you must verify why this vehicle has not had an MOT for over six years. Long-term storage is often more damaging to a complex vehicle like the R230 SL than regular use; expect to find perished rubber seals, seized brake calipers, and potential fuel system degradation.
Ensure you have a professional inspection performed by a specialist familiar with Mercedes-Benz hydraulic systems. Negotiate the price heavily to account for the inevitable costs of a full service, fluid changes, and potential replacement of aged components that have sat idle since 2020.
As a 3.7L petrol engine, this SL sits in a high tax bracket and will be thirsty on fuel, likely returning low-to-mid 20s mpg in mixed driving. Insurance for a high-performance luxury convertible of this age can be expensive, though classic car insurance policies may offer a more affordable route if the car is used sparingly.
Maintenance costs are the primary concern for this specific vehicle. Beyond standard consumables, you must budget for the complexity of the SL's systems, including the ABC (Active Body Control) suspension, which is notoriously costly to repair if it has failed due to lack of use.
Your primary focus must be the condition of the hydraulic suspension and the retractable roof mechanism. Since the car has not been tested since 2020, check for any fluid leaks under the car and ensure the roof operates smoothly without hesitation or warning lights on the dashboard.
Inspect the condition of the tyres, as even with low mileage, rubber compounds degrade over six years. Check the underside for corrosion, as sitting in storage can sometimes trap moisture against the chassis, and verify that the engine starts cleanly without misfires or excessive smoke, which could indicate failing seals or stale fuel.
This 3.7L petrol Mercedes-Benz SL is an intriguing prospect due to its remarkably low recorded mileage of 37,774 miles. However, the absence of MOT records since early 2020 is a major red flag for any prospective buyer. The car's long-term storage status means that while the bodywork and interior may be preserved, the mechanical components likely require extensive recommissioning.
The R230 series SL is known for complex electronic and hydraulic systems that require consistent maintenance to remain reliable.
