To try and reduce the clutter I'm creating on the forum, I will keep all GMT900 product information contained to this thread.

SUVs(and Avalanche):
LS (note: black door handles and mirrors):
Z71 (note: the door handles are unique, they aren't entirely chrome)
Early 2007 LTZ:
I'm unsure when the changeover to the chrome mesh grille, chrome handles and mirrors took place, but all these early models with VIN/build stickers visible show 6/2006, 7/2006 or 8/2006 production dates. I will keep looking to try and lock this down further.
Here's a chromed LTZ with a 12/2006 build date:
Another thing to note on chromed vs. non-chromed LTZ is the center console changed slightly. The chromed models added some faux wood trimming over the cup holders and empty spaces. The non-chrome have the same center console as an LT.

NEW YORK – It is no coincidence that the 2012 GMC Yukon, Yukon XL and Sierra Heritage Editions will debut at the New York Auto Show. A century ago, the GMC name first appeared on the front of a truck at this very same event.
Commemorative exterior badges on the doors of these special models feature the original GMC logo design that debuted on the 1912 range of models, which included gas- and electric-powered trucks designed for the most demanding among early drivers. The script is surrounded by the words “Heritage Edition.”
2012 Heritage Editions will be offered on Sierra 1500 Crew Cab, Yukon and Yukon XL models in SLT trim. Three colors will be available – a new, exclusive Heritage Blue ($195), White Diamond ($995) or Onyx Black (no additional cost). Interior colors for the Yukon are Ebony and Light Tan.
