I always tell people to ride in the cars they are looking at.
With the FFR, a lot has to do with who/how the car was finished. I have seen some VERY nice FFR's (go to DVSF III). If you ride in the ones you like the looks of, it should tell you how the car will handle after the build.
I always liked "the look" of the SPF's, and after the ride in one (after riding in many Cobras), I made up my mind. Errrrrrr should I say my wife made up my mind.........But that is another story
