We've had our GLK350 AWD for a few weeks and are pleased overall with the purchase. The car inspires head- turning everywhere we go, and the driving experience is top-class. Seat comfort is exceptional, as are the quiet ride and visibility on all sides. Build quality seems excellent, other than a finicky rear liftgate. Sometimes it stops after raising about 6 inches - could be user error, but everything else is working great. Fuel economy is abysmal, as advertised. Hopefully rumors of a diesel version are true. Other minor complaints include the spongy brakes (you really need to lay on them, unusual for a German luxury car), lack of PDA holder, cruise wand placement and lack of RT traffic.
