The overview
For 2017, the updated SLK also gets a new name: SLC. It features a retractable hardtop that does a great job at keeping the interior quiet. The new SLC300 uses a more powerful 2.0-liter engine coupled to a nine-speed automatic. There is a more powerful V6 SLC43 version. The SLC has crisp, enjoyable handling, with rock-solid body control and communicative steering. It can be both challenging and rewarding when driven on a track. The ride is firm but refined enough even for lengthy trips. The tight cabin is well-finished, with excellent seats that feature warm-air vents in the head restraints to keep your neck warm during chilly top-down drives. 2020 was the final year for this stylish convertible.

Behind the data
Latest source update: September 11, 2026
Vehicle summaries, specifications, pricing and ratings come from Consumer Reports vehicle records. Auto Guide groups these records by model and reported generation start year.
Available years are listed explicitly. Gaps do not imply that a model was discontinued. Prices are source estimates, not live offers. No first-hand road test by Auto Guide is claimed.
