 Pros: I love the feel of this car when driving. It's solid with great acceleration. I also like the fact that you can put the car into the "hold" position (while stopped at a light for example) and the car will temporarily cut off theoretically saving on gas. Once you put your foot on the accelerator it kicks back into drive seamlessly. It's a quality made vehicle, and overall the drive and performance is great. Cons:  For several years, I drove a BMW X5 and a Lexus RX350 before purchasing this vehicle. As one reviewer mentioned, it took concentrated maneuvering to get either the Beemer and Lexus into my garage because of their larger size.  I bought the GLK thinking it was marginally smaller and therefore not as much trouble to get in and out of the garage. It took a while to notice that it's not just marginally smaller, its tremendously smaller than either the Beemer or the Lexus. In fact, the interior room is so much smaller that I sometime have trouble getting in and out. The leg room in the backseat is a joke. My son is only 5'10", but I had to move all the seats forward when bringing him home after surgery. I couldn't get his size 11 feet into the back comfortably. Not only is there insufficient leg room, but theres no room to just put "stuff". You know- stuff - like things you would normally keep in your glove compartment besides the owner manual. Forget it. This is the smallest glove compartment I've ever seen. The owners manual barely fits. If you have other "stuff" to put there you'd better think of something else. Don't expect to have room in the side pockets or the pockets on the back of the seats either - almost non-existent. The armrest in the middle has some room but not by much.I'm on the road a lot. While I drive I like to listen to audio books via my Iphone. I expect the bluetooth to pick up the book as soon as I get into the car. That's the way it worked on the previous two vehicles. Not with the GLK. Sometimes my book starts automatically. Sometimes it doesn't. It drives me crazy when I'm on a long stretch of highway and lose the signal. That's happened more than a few times. Driving and trying to manipulate the small letters (I wear reading glasses and can't see as well as I used to) on the dashboard or with the little "wheel" to try to reconnect bluetooth isn't always easy. Just trying to see whether I'm pushing the Navi, Radio, Disc button is beyond my vision and graphics be damned they are not all that intuitive. It's been a year since I purchased the vehicle. It has less than 6K miles on it. As I now contemplate trading it in, I've found that the value of the car has dropped by at least 35% after only a year. I got 60% on trade for my Lexus - after 5 years!  Turns out the GLK doesn't hold it's value.  I'm disappointed in that, but you live and learn. Overall, the GLK drives smoothly, accelerates quickly but buyer beware theres a lot of little annoyances that may not make it worth the initial high cost.
