I love my Mercedes-AMG SL43! I was unsure if I would like the ride and handling of my car after watching YouTube test videos on the latest (R232) SL43 but I need not have been. As for the new dashboard, the new switches and buttons are a refreshing change and an absolute pleasure to use! The buttons work without a problem with the ingenious haptic feedback that is given. Mercedes often takes the lead in car manufacture. Soft close doors first appeared on the S-class now Rolls Royce, Bentley and many others have adopted them. The new Mercedes switch gear will no doubt be adopted by other manufacturers eventually. I cannot recommend my (R232) SL43 enough. It is in fact replacing my SLK 280 from 2007 which has only covered 16k miles so I am letting my sister have it in her family as a future classic. The SL43 rides and handles beautifully and if, like me, you want a replacement for an SLK or SLC this is the right car for you. The new fabric hood makes it easier to style a great car which looks stunningly like the original 300 SL roadster from the 1950's and the SL43 carries on where the 190 SL and SLK and SLC left off! The SL43 is a stunning well made car that I have no hesitation in recommending! It's also great as a 2+2 for children in the back of the car!

The AMG line Mercedes SL400 is a superb sports convertible with great acceleration, handling and exciting to drive. I covered 3,000 miles touring Scotland on two weeks holiday and felt completely safe and comfortable at all times.

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 hardtop, which transforms the car from a refined coupe into 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.
The SL excels as a dignified grand tourer rather than a sharp sports car. Whilst it may not match the Porsche 911 for dynamic handling or the Bentley Continental GT for outright luxury, its rounded character makes it difficult to fault. The V8-powered SL 500 offers the best balance, whilst the AMG variants deliver thunderous performance. Running costs are substantial, with insurance in group 50 and fuel economy ranging from 26.4-29.7mpg depending on engine choice. However, well-maintained examples hold their value and feel like proper high-end roadsters even with significant mileage.
Best for: Buyers seeking a versatile luxury roadster and coupe in one, those planning cross-continental cruises or weekend escapes, and drivers who value comfort and adaptability over outright sportiness.
Not ideal for: Budget-conscious buyers, those prioritising dynamic handling like a Porsche 911, or drivers concerned about high running costs and insurance premiums.
Comparison vs Key Rivals
| Vehicle | CarGurus Expert Rating | CarGurus User Rating | Good/Great deals % | Overall CarGurus Rating |
|---|---|---|---|---|
| Mercedes-Benz SL-Class | 4/5 | 4.6/5 | 40.3% | 4.3/5 |

| Porsche 911 Cabriolet | 4/5 | 4.6/5 | 13.2% | 4.2/5 |
The Verdict
You should buy the SL-Class if: You seek a versatile luxury roadster and coupe in one, plan cross-continental cruises or weekend escapes, and value comfort and adaptability over outright sportiness.
Consider alternatives if: You prioritise dynamic handling like a Porsche 911, seek outright luxury like a Bentley Continental GT, or are concerned about high running costs and insurance premiums.
Competitive Position: The Mercedes-Benz SL-Class (2012-2020) is a hugely capable and desirable roadster that stands apart from its rivals through its unique dual character. Whilst it may not match the Porsche 911 for sharpness or the Bentley Continental GT for outright luxury, its rounded appeal makes it difficult to fault. The folding metal hardtop is a defining advantage, offering the refinement of a coupe with the open-air theatre of a roadster. As a dignified grand tourer, the SL excels at cross-continental cruising and weekend escapes, combining comfort, performance, luxury and open-air charm in a way few cars manage quite so well.
