More details needed like the going prices around where you are, do you want a low mileage garage queen or a driver, what is your budget etc...
This is a hard one though... I'd probably get the Cobra personally just to have the numbered car. They are faster right off the bat too but if you really like the look of the New Edge the 2V might be the way to go. Up to you man.
