“It's a luxury sportscar with lots of room inside and is still very fast. The top down on the car is just as sharp as the top up. It's not just a summer car because it's a convertible, it has heating elements so use it in the winter too! I do!”
2020 Mercedes-Benz SLC: What's New, Specs & Features
Last updated August 4, 2026
The most important change for the 2020 Mercedes-Benz SLC is standard blind-spot monitoring across the lineup. Mercedes also adds SLC 300 and AMG SLC 43 Final Edition models for the roadster’s last U.S. model year, while the engines, folding hardtop, and basic cabin design carry over.
About the 2020 Mercedes-Benz SLC
R172 generation (the third SLK generation, renamed SLC for 2017); final model year in the U.S.
Mercedes-Benz positions the SLC as its compact two-seat luxury roadster: a rear-drive convertible built around open-air driving, classic long-hood proportions, and the added security and quiet of a folding hardtop. Compared with pure sports cars, its appeal is broader everyday usability. Compared with the larger SL, it is the smaller, more approachable Mercedes roadster, aimed at drivers who want style, prestige, and top-down enjoyment without stepping into a bigger grand tourer.
The SLC 300 is the more relaxed version of this two-seat roadster, with a 241-horsepower turbo four-cylinder engine, a nine-speed automatic, and a power-retractable panoramic hardtop. The AMG SLC 43 brings a stronger V6 and a more intense character, while Final Edition versions of both models mark the end of the SLC’s U.S. run.

2020 Mercedes-Benz SLC
(72 reviews)
“DO NOT BUY THIS CAR. THE BRAKES SQUEAK AND I WAS TOLD THAT IS WAHT HAPPENS WITH AMG BRAKES. IT HAS BEEN IN SERVICE CONSTANTLY SINCE I GOT IT USUALLY A WEEK AT A TIME AND THEY don't FIX IT.”
“There is an acute lack of storage. The trunk is nearly unusable. The infotainment system is NOT user friendly. The seal belts are hard to reach and the buckle snaps back past the seat holder out of reach.”
