About the 2020 Mercedes-Benz AMG SLC
3rd generation (R172; 2012-2020 US model years), final year; facelifted and renamed from SLK to SLC for 2017
Mercedes-Benz positioned the SLC as a compact two-seat luxury roadster that combined open-air driving with the security and quietness of a folding metal roof. The AMG version added strong rear-wheel-drive performance without giving up heated-seat comfort, neck-level heating, and everyday road manners. Its defining difference from soft-top rivals was the coupe-like power hardtop, paired with a small footprint and a powerful twin-turbo V6.
The 2020 AMG SLC is a compact, rear-wheel-drive performance roadster with a power-folding metal roof. Its SLC 43 AMG trim pairs a 385-hp twin-turbo V6 with a nine-speed automatic, AMG-tuned suspension, larger brakes, and an active exhaust. Heated sport seats, neck-level heating, a panoramic roof panel, and Harman Kardon surround sound add everyday comfort.

“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.”
“It is an fast, aggressive, incredible sounding luxury performance vehicle. It handles incredibly and is a true driving experience. It is a very easy to use convertible that looks great with the top up and down. The AMG engine and the sound it makes is worth every penny! I would tell anyone considering the MB SLK 43R......drive it and you will be sold.”
