2012 Mercedes-Benz GLK-Class

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.

Based on the C-Class platform, the GLK has a smooth 3.5-liter V6 that delivers quick acceleration and 18 mpg overall on premium fuel. Ride comfort is solid and tranquil when cruising, but the low-speed ride is a bit unsettled. The GLK handles fairly nimbly, but doesn't shine at its limits. The high, upright seating position affords a commanding view out through the big windows. The front seats are firm but well-shaped. Leg room in the rear is stingy at best and the wide doorsills impede access. The controls are better than in many Mercedes-Benz models, but some still aren't exactly logical. A 2013 freshening considerably improved the car, with a new V6 engine that increased fuel economy to 21 mpg overall and more luxurious interior materials. A four-cylinder diesel engine is also available.
