So, I found some back up CD's from 2006. They contain a bunch of cool stuff from C&G past, as well as stuff from all over the internets. Most of this has been lost in the sands of time, so I think I will share some here.
First up, is a repost from the "New GM" thread...
Here is the Pontiac G6 we were supposed to get, before Bob Lutz had them simplify it!

Popular Mechanics spy pic shows a nearly finished product!
A wall of Corvette renderings! This was snuck out of the studio during C6 development!
Early C6 model (shown at a Miami consumer clinic):
This image comes from the Canadian Chevrolet Cobalt launch site from 2004!
