I've had a series of high-end super SUVs, including Landcruisers, Land Rovers, Lexus LX470, and I tested all of their most recent models before buying the QX56. This Infiniti is the best by far. It is huge on the inside, FAR larger than a Landcruiser/LX570 or Range Rover. Far more luxurious and full-featured than any other large SUV other than the Range Rover. Everything is well thought out. The exterior is handsome, especially the gigantic chrome grill and chrome roof racks. These trucks are rare enough to continually look fresh, unlike say an X5. At 5000 mile it is still solid, rattle-free, and a joy to drive. I don't think there is a better large SUV out there at any price.
Prestigious-looking front grill. Gorgeous wood dash/door accents. Separate folding/removable middle seat in the middle row (acts like a pass- through for kids, or can fold up for 8-passenger seating). Power fold-flat 3rd row. Logical controls. Quality feel everywhere. Simple Nav screen. Bluetooth.
Storage behind 3rd row seats would be easier to use without the lift-up hideaway. I would also prefer a split rear hatch like the LX570. Running boards could be a bit sturdier. Parking sensors should be in front bumper too, not just rear bumper. DVD player should be easier to control from dash.
