I gave my Acura MDX to my daughter and was looking for another solid SUV. Fell in love with the MB GL450 at first sight. Beautiful inside and out. Then saw the 320CDI version and drove it. Couldn't believe it was a diesel. Who would believe that you could have large comfortably luxury in an SUV and get 27 mpg on the highway? I was only worried about recent MB quality surveys on Consumer Reports but felt a little better given that the GL was totally redesigned.
I love size and the looks. Navigation is a little complicated but fine once you get the hang of it. The Comm center gives you more information than you'll probably ever want. It has a great ride with a good road feel. You simply can't believe it's a diesel - no delay starting and it's quiet!
Bluetooth accessory was way too expensive at $350 (should be standard on a vehicle at this price) and the running boards are still back-ordered!
