Upright styling and a high grade of interior materials give the Mercedes-Benz GLK an inviting interior, and four adults will find plenty of space inside for themselves and their carry-ons, but overall cargo space is a little shy of some compact luxury crossovers.
The GLK's front seats are tailored and bolstered with the firmness and support that's a hallmark of German sedans, and taller drivers won't be pressed to find a comfortable driving position, though the sunroof trims out some of the headroom. The second-row seats offer up enough knee room and three children will fit across the bench seat. No third-row seat is offered.
On the spec sheet, you'll see standard vinyl upholstery, but since Mercedes' U.S. dealers clamor for option-rich cars, we doubt you'll ever see a GLK without leather seats.
The GLK's rear seat also splits and folds to boost cargo space, which the GLK needs to better compete with larger crossovers like the Volvo XC60. With the rear seat down, the GLK has a cargo area of 54.7 cubic feet. With the seats folded forward, the cargo space is almost perfectly flat and measures nearly 66 inches long. With the back seat up there's still a very respectable 23.3 cubic feet of cargo space, but the 30-plus cubic feet of space in the Volvo outpace the Mercedes handily.
The GLK combines a high-quality interior with a comfortable and usable cabin that luxury buyers will appreciate. There's nice trim and detailing throughout; though given the lower price point, it's not surprising that the interior appointments, up close, aren't quite up to the level of those in M-B's larger and more expensive SUVs.
