2014 Mercedes-Benz SLK

A 2012 freshening brought a new 3.5-liter V6 and seven-speed automatic, as well as a 1.8-liter turbo four-cylinder with a six-speed manual. The small cabin is well finished, but narrow. On the whole though, we like this car. Handling is sporty and enjoyable, while ride and noise levels are civilized enough to leave you unrattled on a long road trip. The retractable metal top folds away quickly. When it's up, the SLK behaves as a credibly solid and quiet coupe. Safety features include antilock brakes, brake-assist and electronic stability control as standard equipment. The optional "Attention Assist" system warns drivers who show signs of growing tired. Available features for 2016 include optional blind spot monitoring. Additionally, the SLK250 was replaced by the SLK300 for 2016, which brought more power and a nine-speed automatic transmission.

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.
