Elise is untouchable, unless you are on the waiting list from what I hear. I think they are all spoken for during the first round of release in the US.
They are yet another show stopper. People will look at you like you are in a ferrari, etc. Great car for the road courses. The car is very well balanced, not too much power, but the car is very light.
It is all personal preference. I love the interior of the Crossfire. I had considered the Elise, however it wasn't being released until this year. I wanted the Crossfire NOW (last year). I'm still happy with my purchase. Great daily driver. Takes regular road bumps with ease, yet locks in at 90mph, feeling like 20.
