"This is actually my mother's car (I drive a brand that begins with a P), but I've driven it frequently enough to form an impression. Reliability seems to have been a non-issue over 2 years, although a front suspension/shock groan has surfaced recently.
The Mercedes-Benz hallmarks are all here. Cabin is impressively stiff and isolated for the price. Doors shut with a sound that whispers money. 80 mph feels like 50. And so on. Car has the Premium Package w/ Nav, getting typical toys like power tailgate and rear camera. Synthetic seats are a tad rubbery, but TOUGH as nails and do not appear to wear at all. Wood trim and silver accents are old-world-elegant, and the interior is generally angular and conservative. These are what keep my mother going back to the brand. Very Benzo.
Unfortunately, that's where the positives end. It doesn't seem to be any more frugal than the ML350 that it replaced, struggling to reach 23 mpg highway despite weighing 800 lbs less than the ML. Throttle response of a fishing boat. The rudder...it's a rudder. Suspension is very soft and not even well-damped. The car begs for straight lines. Don't think about off-roading with those delicate 19" wheels, which are pretty but a nightmare to clean. Overall, best experienced from the [front] passenger seat. Back seat is tight."
Pros: "handling, interior, bluetooth features, ride, eco"
Cons: "can be a bit pricey, needs more cargo space"

"The combination of quality, luxury and comfort makes for a great overall package. It drives like a car but provides more space and versatility. It wont blow you away with its mileage but what it gets is respectable for the 300+ hp it gives you. It is an incredibly smooth driving machine. The eco stop start feature has far exceeded my expectations. I thought I would be able to notice it every time the motor shuts off but if the radio is playing and you go straight from brake to throttle it takes off without a hitch. However in stop and go traffic it is noticeable. However, with the touch of one button you can shut it off. It handles beautifully in poor weather. The blue tooth connectivity works flawlessly likewise with the audio streaming. Great features! Much better interface than my Chevrolets. If you forgo on many of the "extra" options and just get what you want, it can prove to be a very good value for the combination of quality and luxury that it provides. Overall a great buying decision I feel. Very close to purchasing an Infiniti but I am very happy with the decision I made."
"Worth the wait for the 2013 model changes. Interior is far superior to prior year models. Luxurious, quite and smooth ride even with the 20" wheels. Acceleration in economy mode will start in 2nd gear for fuel savings. Under normal driving conditions, it performs superbly. If I need additional acceleration, I switch to sport mode and the GLK starts in 1st gear adding more torque and quicker acceleration. In ECO mode, the engine will shut off during stops and restart when the brake is released with no interference in acceleration and is almost unrecognizable. If AC is adjusting temperature in Auto mode, providing AC comfort takes priority over engine shut down at stops. All electrical functions are normal. Keyless is great. The only way you can lock keys in car is by using the lock function on the automatic tail gate...dealer said you could never lock keys in car until he did with the tailgate. MBrace unlocked the car. Drove an Audi for 6 years and loved it until I got to 100,000 miles then the car began to break down. Drove the Q5. Sporty, but noisy 2.0 and 3.2 had nothing to offer. Don't believe the man behind the curtain in Consumer Reports. Compare the cars yourself. MB GLK is fabulous. New Pebble Gray with cream and brown interior with pleny of dash wood. Seating in the rear is just as adequate as Audi. Dual sunroofs are filtered for less heat. Less expensive Becker Nav is great. Knob manipulation less complicated than Audi or Lexus. Used USAA Car Buying program and got a great deal. You will enjoy the new GLK!"
"Most of my driving is long distance (1 to 8 hours a trip) with very little stop and go city driving. Valve cover leak that had to be repaired 3 times before they got it right (45k). Transfer case leak at 49k. Constant bulb burnout in all lights (at least 3 times in the front lights and 6 in the tail lights). at 80k I'm now told I need a new transmission/transfer box at $6,000+. To top it off my seat belt stopped working two days ago.
Not a very reliable vehicle. I expected better of a MB as a first (and last) time buyer. If you buy it make sure you purchase the extended warranty."
