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

Pros	Cons
Folding metal roof adds security	Boot space reduces with the roof down
Glamorous looks	Dated and cramped interior
Boot is a reasonable size with the roof up	Not exciting to drive nor comfy to travel in

Quick Summary

The Mercedes-Benz SLC (2016-2020) is a stylish roadster, essentially a rebadged and mildly facelifted version of the third-generation SLK. While it offers a glamorous appearance, its interior can feel cramped, particularly for taller drivers, and boot practicality is significantly reduced when the folding hardtop is lowered. The driving experience is notably laid-back, lacking excitement and comfort, with a tendency to jolt over uneven surfaces rather than glide smoothly.

Engine options include 2.0-litre petrol units (SLC 200 and SLC 300), though these are not particularly engaging. The infotainment system feels dated, but features like the 'Airscarf' neck-level heating are a plus. Running costs are not particularly impressive, with petrol models averaging 30-35mpg, and servicing can be expensive. However, the SLC does benefit from good value retention, making it an appealing option for those who prioritise style and badge appeal.

Best for: Drivers prioritising glamorous roadster looks and the security of a folding metal roof, those seeking a car that holds its value well, or buyers who appreciate comfort features like 'Airscarf'.

Not ideal for: Buyers seeking an exciting or supremely comfortable driving experience, those needing generous interior space or boot capacity with the roof down, or those looking for modern infotainment and consistently low running costs.


Comparison vs Key Rivals



The Verdict

You should buy the SLC if: You're seeking glamorous roadster looks with the security of a folding metal roof, appreciate a car that holds its value well, or value features like 'Airscarf'.

Consider alternatives if: You prioritise an exciting or comfortable driving experience, require generous interior or boot space with the roof down, or are looking for modern infotainment and low running costs.

Competitive Position: The Mercedes-Benz SLC (2016-2020) positions itself as a glamorous, if somewhat compromised, premium roadster. While it struggles to match rivals like the Porsche Boxster for driving excitement or comfort, and its interior and infotainment feel dated, it benefits from good value retention. Compared to an Audi TT, it might be pricier, and a BMW Z4 offers a more modern alternative. Its main appeal lies in its stylish looks and the prestige of the Mercedes badge at a relatively accessible price point, particularly for those who prioritise a folding metal roof over outright driving dynamics or cutting-edge tech.
