With a 6-foot driver, rear seat room is barely adequate for adults, for short trips. This is typical for this car segment, though. see full BMW 3-Series review

TrueDelta Reviews the Seat Room and Comfort of the 2014 Mercedes-Benz GLK

2014 Mercedes-Benz GLK Seat Room and Comfort: Cons
YearComment
Expect the GLK to grow when it is next fully redesigned. A smaller MLK is on the way to battle the upcoming Audi Q3 and just-arrived BMW X1. For 2013, the GLK's body structure remains essentially the same, so rear seat knee room remains just sufficient for a man of average height sitting behind another such man. (Headroom, on the other hand, is abundant.) Among competitors, only the Infiniti EX37 has a tighter rear seat. The Audi, BMW, and Volvo all offer knees another inch or three. Seat comfort is debatable. To my bottom, the GLK's seats feel overly firm. Cargo space is similarly short of the segment average. The GLK's 54.7 cubic feet isn't far behind the Audi's 57.3 but well below the X3's 63.3. That truncated tail has a downside beyond aesthetics. But do these shortcomings really matter? For most people nearly all of the time, there's enough space. see full Mercedes-Benz GLK review

We are a couple with no kids and we rarely have visitors so the cramped rear seating is not a problem. Someone with teenage kids will want to seriously reconsider before getting a GLK. I know my Mom would not appreciate the ingress/egress ease as she has some limited mobility. see full Mercedes-Benz GLK review
