"I looked at the BMW x3, and the Audi q5. This is by far the best because of the options (love mbrace) and the style (nothing looks like it). The Audi is essentially the VW equivalent, and the BMW does have a luxury presence (other than the name). I got the GLK with just about all options (expect for the rear video and parktronic) which gives it presence."
"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."
