The list is a double edged sword. It can show GM an the stockholders there is a long list of people waiting to buy the car... But GM should not become over confident and be led to believe people will be willing to buy an overpriced car over list and without the comforts I expect in a car.
Good point, silvercorvette. Although I am very interested in the Volt, I haven't signed onto the list because I don't want to commit to anything until I have seen the Volt, and after it has been out for a while. I hope the Volt is everything I imagine it could be; time will tell. . .
