I'm a biased proponent. My wife owned a Tesla S100D until last summer and it was a comfortable, reliable, and cost effective vehicle. If the CT can live up to that (after the bugs are worked out)--I'll be very interested.
I like it, but I am not an "early adopter." I was also one of those guys who thought DeLoreans were cool as a kid.
I'd wait about 3-4 years for the guinea pigs to work through the teething pains.
