 If you are used to quality made, well-thought-out vehicles, go elsewhere.  Mercedes has dropped its ability to think and innovate to save money on this vehicle.  It's simple to look at the previous generation and see that that was a better car.  The GLK had bigger windows, bigger engine, more comfortable seating, and styling that doesn't look like they used an ugly Acura as a template.  The windows on this car are tiny, which is what I would expect from a current econobox.   The styling of this car suffers from the awkward tiny windows and bulbous rear end.  The COMMAND navigation is the worst I've ever used in any car I've owned. It actually shows you advertisements while you are navigating for Starbucks, Dennys, and others.  You can't turn that off.  The controls are terrible compared to BMW i-Drive or even just a Ford. It takes so much work to just advance to the next track of the music you are listening to, you'll end up just shutting off the stereo.  I'm a software engineer, and I find the thing so backwards and bizarre to use I just can't imagine someone who isn't a techie finding it simple.  They have all the features ticked to be on par with BMW but each are all done so poorly.  It's just an endless disappointment.  It has strange quirks too.  Start closing the sunroof and get out of the car, and it stops closing - but you can close it from the outside.  Why?   The Mercedes Me app and the COMMAND internet access is a total joke.  Both take forever to load.   If you really want this car, get it with no electronic options ticked.  Don't get navigation for sure.  By the time the voice guidance completes its total blather and gets to the actual turn, you're already past the turn.  It doesn't work well enough to justify the advertisements on screen either.  Get it bare bones, so there are fewer things to be disappointed by.  The engine, transmission, seats, and steering are just excellent - better than my 5 series.  The rest of the car is just a joke.  Also, spend some time in the seat.  The forward facing headrests are what you would expect from a Honda, not a Mercedes Benz.  The prior model GLK had active headrests, which don't place you in an awkward position.   MB cheaped out and used passive headrests for this car.  Prior to this car, I owned a BMW 328i Wagon (base), a BMW ActiveHybrid3 (Sport), and a BMW 535D (every option).   I have never sat in a Lexus and found it to be luxurious.  Acuras look and feel cheap and tinny to me.  I'm not stuck up, I just want the quality and innovation to be present when I pay 50K for a car.  I encourage you to demand more and get the best thing you can find with few compromises.  In that light, this GLC is just junk.   I just traded it in after only 4 months with it.
