Just got a graystone LTZ with titanium interior, 6.0L/4.10, DVD, Nav, etc. Very nice truck. Coming from from an 04 Burb and an 01 Burb, this is a much nicer riding and driving vehicle. Things I'm not sure about are the fewer cubbys and pockets for stuff on the inside, and the cupholders seem to be smaller. Those are little things though. More pictures later if interested.
