Mercedes-Benz SL-Class (2012-2020) Pros and Cons

Pros	Cons
As capable as it is desirable	Not as dynamic or sporting as a Porsche 911
The benefits of a roadster and a coupe in one	High running costs
Epic performance of AMG SL65	AMG models can overstretch the chassis

Quick Summary

The Mercedes-Benz SL-Class (2012-2020), known as the R231, is an iconic luxury roadster and coupe that combines the best of both worlds. Its defining feature is the folding metal Vario-roof, which transforms the car from a refined coupe to a glamorous two-seat roadster in less than 20 seconds. Built almost entirely from aluminium, the R231 benefits from improved performance and fuel economy compared to its predecessors. With 485 litres of boot space with the roof raised and 364 litres with it folded, the SL remains surprisingly practical for a weekend away, though packing requires consideration of the roof mechanism.

The SL excels as a dignified grand tourer, perfect for cross-continental cruises or weekend escapes with the roof down. Whilst not as sharp to drive as a Porsche 911 or as luxurious as a Bentley Continental GT, its rounded character makes it difficult to fault. The V8-powered SL 500 is the sweet spot, offering strong performance and refinement, though running costs are substantial across all variants. Standard equipment is generous, particularly on later Grand Edition models, featuring Nappa leather, Airscarf heating, and optional smartphone integration on newer examples.

Best for: Buyers seeking a versatile luxury roadster and coupe in one, those prioritising comfort and refinement over outright sportiness, and drivers planning European grand tours or weekend escapes.

Not ideal for: Budget-conscious buyers concerned about high running costs, those wanting sharp driving dynamics comparable to a Porsche 911, or drivers seeking maximum practicality with larger luggage requirements.


Comparison vs Key Rivals



The Verdict

You should buy the SL-Class if: You seek a versatile luxury roadster and coupe in one, prioritise comfort and refinement over outright sportiness, or plan European grand tours and weekend escapes.

Consider alternatives if: You are concerned about high running costs, want sharp driving dynamics comparable to a Porsche 911, or require maximum practicality with larger luggage capacity.

Competitive Position: The Mercedes-Benz SL-Class (2012-2020) is a highly desirable luxury roadster that stands apart from its rivals through its unique dual-character design. Whilst the Porsche 911 Cabriolet offers superior driving dynamics and the Bentley Continental GT Convertible provides greater luxury, the SL strikes an impressive balance between comfort, performance and versatility. The BMW 6 Series Convertible offers better value with more good/great deals available, but the SL's iconic status and refined engineering make it a compelling choice for those prioritising adaptability and open-air charm. Its greatest strength lies in its ability to excel as both a dignified grand tourer and an engaging roadster.
