This thing is going to be a flop. It is way, way to big and heavy and 'over-styled' to be taken seriously. It will be useless as a daily driver.
The Mustang, while similar in size, 'seems' to me to be much more user-friendly and 'capable' for daily tasks.
Unfortunately it will become a media 'sensation', as GM will most likely go under just as this thing ramps up for production, creating endless stories about how this car 'could have saved GM, but never got the chance...'
It will also become one heck of a collector car - imagine what one of these will be worth in 20 years as 'a last great example of what GM was about...'
