2018 Mercedes-Benz SLC

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.

Brand context

About Mercedes-Benz

Most Mercedes-Benzes give their owners industry-leading comfort and technology. The cost of that experience is an expensive base price with expensive options and below-average reliability. The brand produces a wide variety of vehicles for the U.S., including coupes, station wagons, sedans, convertibles, and even two-seat sports cars. Its two- and three-row SUVs that we’ve tested have powerful engines and interiors that are roomy and quiet. Generally, Mercedes-Benz fit and finish, inside and out, is exceptional and helps justify prices. Mercedes-Benz’s EVs range from compact to large three-row SUVs. Across the lineup, controls for the complex climate and infotainment systems aren’t as intuitive as we find in other luxury vehicles. Like most European luxury brands, used Mercedes-Benzes can have expensive out-of-warranty repairs, although Consumer Reports has found used models with above-average reliability.
