Heck, I'm not expecting to be in the market to buy one of these, so I could go either way about how it appears to me. Generally I like it, but it's not at all what I would consider as a perfect "upgrade". And if history is any guide, you probably don't want to be the first on your block with ANY new design. I would NEVER want to buy the first year's production of any new generation. Basically all of those buyers and drivers are the beta testers for the new design.
One thing I am curious about, though, is if the paint job done on the car in the above video is a custom special job, or if GM finally got the kinks worked out of their standard paint jobs to eliminate that blasted orange peel texture.
I guess it will take a couple of years of owner's driving them before the kinks and wrinkles become public knowledge.
