Took delivery of my 2017 CCSB LTZ Z71 on 1/6/17 after a couple of days of calls/emails with the internet sales manager at a local dealer. 7 miles on the clock when I arrived for my test drive, 15 when I returned it, and 18 when I took delivery 4 hours later.
Plans are relatively tame at this point. First up will be tint, followed shortly by a level (currently debating between 2 and 2.5, also between 275/60r20 or 275/65r20 BFG AT KO2s). From there I'll probably keep it pretty low key for a while. Down the road exhaust and a remote light bar behind the grill might come in to the equation.
