I bought the LTZ New Year's Eve, and I am very pleased with this vehicle. I drive a lot of highway miles and average about 23 mpg, driving 65 mph. It drives smoothly, handles well, though turning radius isn't the tightest. With the back seat pulled all the way forward, there is plenty of cargo room, and with it all the way back, plenty of leg room. The Pioneer sound system w/subwoofer gives premium sound. I would suggest adding more storage compartments. The driver's visor extends, but the passenger's does not - kind of odd.
Leather and power seats, steering wheel radio controls, 6 disc changer/XM and Pioneer sound system, heated seats, fuel economy (for an SUV)
More storage compartments, passenger visor extension, ability to open rear glass seperately on lift gate, remote opener for lift gate
