Thank you all. Yes it is the AWD CXL/CXL Plus with the stock Bose radio, cashmere/cashmere metallic, with air suspension, rear air compressor, tow package, 3.72 gears with G80 locker (YESSSSSS), rear audio/HVAC controls, and the smoker package with unused cigarette lighter and ashcan found in the rear storage! There are some issues that need fixing: both sets of rear trunk struts are dead, one of the ECU grounds behind the battery was unplugged (!), the engine airbox wasn't assembled correctly and threw up a CEL, the oil pressure switch probably needs replacing, the HVAC blend door needs resetting as it doesn't blow to the face, and the Onstar dimming mirror has broken at the pivot point and probably needs replacement.
So far it's a nice big tank that cruises at 2k RPM at 65mph. I plan to fix all of the items I mentioned, use it as a weekend car trip wagon, and want to add a LED light bar behind the stock plastic grill.
