I have a 1377 number, I anticipate late 08.
I think that is very easily done. But, I also think they will have a 20% or more attrition rate, and I think they can build more cars then they say. The limited availability thing is just part of marketing the car. Of course, there is a limit, but I think it is really around 40,000 units.
We will know if I'm right a year from now, but I would take a bet on them selling 40k this year in the US.
