I have had the GLK for about 1 week now after driving a BMW X5. It has everything..I wanted something smaller in AWD/SUV that handled like a sports car, GLK is smaller, drives like a car but you sit a bit higher. This is definitely a smaller SUV than a BMW X3. Handles well, not as smooth driving as X5, but much better drive than a BMW X3 which I also have owned. Takes bumps well, looks classy and different than everything else in a SUV on the road. Navigation is easy to control, bells and whistles are plentiful but not too difficult once you review the manual. Gas mpg about 18 for city/hwy mixed driving. I'm 5'3" so getting in and out is easy for me which was an important consideration.
