I've now worked myself up to the position where I may be ready to put down the deposit for the Model S. One thing that holds me back is that the dilemma that accompanies any technological purchase - in a year's time the product will probably be better and cheaper.
There are certain disadvantages to being a very early adopter for EV technologies, such as the current lack of infrastructure. Battery technology, too, will only improve, but these are things I understand and can live with.
What I'm more worried about is the improvements made to the car over the first couple of years. From reading some of the threads about Roadsters, it seems that quite a lot of changes were made between early cars and the later ones. Whilst manufacturers will never intentionally make cars worse, it seems that some of these changes were fixes to things that maybe ought to have been right in the first place. Given the current 18-month lead time to get an 'S', I'd hate to have to get it knowing that not only did it have glitches, but that the next version was already announced and it included fixes.
Can anyone describe the evolution of the Roadster and comment on whether the knowledge gained can be applied to the 'S' directly? Did the Roadster use the Alpha/Beta/RC(?) product development lifecycle?
