I'm assuming people have seen the new video on Vimeo featuring one of the alpha cars out driving on a road course. http://vimeo.com/18614767
First impression: Gorgeous!
Second impression: I liked the prototype's front fascia better. The more aggressive lines of the alpha's lower front spoiler are not as attractive to me, and I also miss the Tesla logo in the front grille area.
I'm sure all of this is subject to revision, so this is just a little feedback from a reservation holder!
