If it provides enough range for a few days to and from work (100 miles) and gets up to 70mph on demand... for a reasonable price premium, of course... I'll be all over it like white on rice.
I can't currently afford $40k for a LiV Dash, but if the Dash can be produced in small quantities for that much, surely Daimler-Benz can bring it down to 25-30k. I also want a decent warranty, even if I have to pay extra for extended terms. Multiple price points, I can deal with. In two years I can probably afford a $30k electric car.
Oh, and keep it Smart small. I love the size of this thing.
