My concern is with diluting the W-body content. We're here because we want to specialize in W-body; losing that specialization would eliminate any reason for me to log on.
The newest vehicle I own is a 2003; GM has probably lost me as a customer until that vehicle won't run reliably because they've decided to follow political correctness or crazy styling instead of building stuff I want to buy. There's not a car in the stable that I have any real interest in. Pretty-much the same with the trucks. If you need the tailgate to multi-function as a step ladder...the truck isn't designed for use, it's designed to "look mean". I don't need that.
Linking to other GM platforms would be a total waste of bandwidth for me. I'm already on forums that specialize in other GM brands; what they have in common in that there's little content for newer crap. It's all Chevy-Pontiac-Olds-Buick-Cadillac pre-1999; and in most cases largely pre-1980.
"Global personal transportation" and "alternative powered vehicles" are "politically-correct JUNK", and that is what I DO NOT WANT.
