Got the 9-7X 5.3i this past June for my wife. We really like the styling, the front end is clean and the lowered suspension gives a sporty look. Definitely a better look than the other platform-mates. Get a lot of compliments as well.
Styling, large wheels, handles better than most truck-based SUVs. Acceleration is great with the V8. Like the interior details - seat stitching, soft dash materials, quietness, air compressor. HID headlamps, nav system, Stabilitrak, XM.
HATE the DRLs, but worse is the ridiculously large key/keyfob unit. They couldn't have made it retract like the VW/Audi ones? In daily use this is my biggest complaint. I also think that for $45K it should lose the mast antenna. Dash-mounted cupholder doesn't hold anything (but looks cool!).
