Mercedes-Benz SLC Mk1 (2016-2020) Pros and Cons

Pros	Cons
Folding metal roof adds security	Boot space shrinks with the roof down
Glamorous looks	Dated and cramped interior
Compact and easy to live with	Neither sporty nor especially comfortable

Quick Summary

The Mercedes-Benz SLC (2016-2020) is a compact two-seat roadster with a folding metal hardtop, rear-wheel drive, and a more relaxed character than sharper rivals. Originally launched as the SLK in 1996, the SLC represents the third generation renamed to align with Mercedes-Benz's model range. The folding metal roof provides coupe-like refinement and security when raised, whilst allowing proper open-air motoring when lowered. With the roof closed, boot capacity is 335 litres; with it down, this reduces to 225 litres. The SLC is reasonably practical for a compact roadster, though taller drivers may find the cabin tight.

The SLC offers a relaxed cruising experience rather than sharp sports car dynamics. Early versions featured a wider engine range, including the SLC 180 and SLC 250d diesel, whilst later Final Edition models were limited to the SLC 200, SLC 300, and Mercedes-AMG SLC 43. The SLC 200 and 300 use 2.0-litre turbocharged petrol engines; the AMG SLC 43 features a 3.0-litre V6. Fuel economy ranges from around 40.4mpg (SLC 200 manual) to 32mpg (AMG SLC 43) officially, with real-world figures closer to 30mpg. The SLC's folding metal hardtop, compact size, and Mercedes badge make it desirable as a stylish, comfortable used roadster.

Best for: Buyers seeking a stylish, glamorous roadster with the prestige of a Mercedes badge, those who value the security and refinement of a folding metal roof, and drivers prioritising comfort and ease of use over sharp handling.

Not ideal for: Enthusiasts wanting sharp sports car dynamics comparable to a Porsche 718 Boxster or BMW Z4, drivers requiring a spacious interior, or those seeking the latest infotainment technology and modern cabin design.


Comparison vs Key Rivals



The Verdict

You should buy the SLC if: You value a stylish, glamorous roadster with Mercedes prestige, appreciate the security and refinement of a folding metal roof, and prioritise comfort and ease of use over sharp handling dynamics.

Consider alternatives if: You seek sharp sports car dynamics comparable to a Porsche 718 Boxster or BMW Z4, require a spacious interior, or want the latest infotainment technology and modern cabin design.

Competitive Position: The Mercedes-Benz SLC (2016-2020) occupies a unique position in the compact roadster market. Whilst it lacks the sharp handling of a Porsche 718 Boxster or the driver engagement of a BMW Z4, it offers distinctive charm through its folding metal hardtop and Mercedes badge. The Audi TT Roadster provides better value and more modern styling, yet the SLC's coupe-like refinement and compact practicality remain appealing. The SLC is best suited to buyers prioritising style, comfort, and open-air motoring over outright performance, making it an excellent choice for those seeking a relaxed, glamorous roadster experience.
