I just saw this on Sympatico as well. I was about to start another thread but saw your post.
I found this part interesting:
And while it seems odd to rebadge a vehicle that's distinctively Pontiac as a Chevrolet, it really isn’t that big of a problem. The G8 is currently sold as a Chevrolet in various markets, so the inserts for the grille, and interior already exist. For instance, in the Middle East, it’s marketed as the Chevrolet Lumina.
