I own a 2002 360 Spider F1 and love it. I enjoy the topless crusing and the car is plenty fast for the laws I am willing to break. My dealer has offered me to swap my car ($ difference pending) for a 2004 Challenge Stradale. I have read up on the Stradale, but never driven one. The rareness & performance of the Stradale is attractive, but the comfort & added sellability (I think) of the Spider is also attractive. Any comments from anyone familiar with both vehicles.
