Mercedes-AMG SL (2023-present) Pros and Cons

Pros	Cons
Glamorous looks	Hugely expensive
Really good to drive	Adaptive cruise control costs extra
Lavishly equipped	Rear seats cramped

Quick Summary

The Mercedes-AMG SL (2023-present) is a two-seat open-top sports car that blends luxury grand-touring with serious performance. This seventh-generation model represents a significant evolution, becoming more aggressive and sports-focused than its predecessors. With its striking long-bonnet design, fabric soft-top roof, and the addition of occasional rear seats, the SL offers a distinctive alternative to rivals like the Porsche 911 Cabriolet. Engine options include a 2.0-litre turbocharged four-cylinder with 375bhp in the SL43, a 4.0-litre twin-turbo V8 with 469bhp in the SL55, and 577bhp in the SL63. All models feature a nine-speed automatic gearbox, with V8 variants offering four-wheel drive and rear-wheel steering for the first time.

The SL delivers impressive driving dynamics with theatrical performance and refined comfort, making it an effortless long-distance cruiser. Handling is playful and engaging, though not quite as sharp as the Porsche 911. The cabin is beautifully finished with deeply sculpted seats, and the 231-litre boot provides adequate space for weekend trips. Technology is comprehensive, featuring an 11.9-inch MBUX touchscreen with augmented reality navigation, Burmester sound system, and wireless charging. However, the SL commands premium pricing—the SL63 exceeds £170,000—and fuel economy is modest at 21.4mpg for V8 models. Depreciation can be painful, particularly on the SL63, making nearly-new examples a more sensible investment.

Best for: Buyers seeking a glamorous, well-equipped roadster with theatrical performance and refined comfort, and those wanting a distinctive alternative to the Porsche 911 Cabriolet.

Not ideal for: Budget-conscious buyers, those prioritising fuel economy, or drivers concerned about depreciation and running costs on V8 models.


Comparison vs Key Rivals



The Verdict

You should buy the SL if: You desire a glamorous, well-equipped roadster with theatrical performance and refined comfort, and want a distinctive alternative to the Porsche 911 Cabriolet.

Consider alternatives if: You prioritise fuel economy, wish to minimise depreciation, or are concerned about running costs on V8 models.

Competitive Position: The Mercedes-AMG SL (2023-present) is a compelling luxury roadster that combines stunning aesthetics with impressive driving dynamics and lavish equipment. Whilst it commands premium pricing and doesn't quite match the Porsche 911's handling finesse or the BMW 8-Series' value proposition, the SL's theatrical performance, refined comfort, and distinctive design make it a highly desirable choice for those seeking something special. Nearly-new or used examples offer the best value, allowing buyers to enjoy the SL's impressive thrill factor whilst avoiding the steepest depreciation. For buyers with sufficient budget and a desire for glamour, performance, and refinement, the SL represents a worthy investment.
