My wife and I were sold on the Mercedes GL-450 until she drove the QX56. Not only was the hype of a Mercedes false, but the QX56 was superior. We only wish they offered the Intelligent Key allowing entry wihtout pressing any buttons. Power folding seats would also be nice. Howevver; these features are not worth the $20k difference of the Mercedes. We are so happy we chose this vehicle over the Mercedes. If you are in the market for a large SUV, you MUST drive this one! Also, the Infiniti service is second to none.
Styling is very different. Room and comfort is the best out there. Navi is awesome and the Voice recognition is fast and very accurate. Seats are soft and all guages are very visible. Bluetooth is a snap to setup and the stereo is easy to work.
Larger DVD screen and larger Navi screen. They look small in this big vehicle. Auto locking and unlocking doors, power rear folding seats and Intelligent key standard. Could have more wood trim for this class. Should offer headrest DVD also, center DVD blocks rear view sometimes.
