Hi Eric,
Front: i would prefer B. Always dreamed of a car that looks like the Crossfire Concept car 1.0.
Side view: I like the side view of Design C more than B. That's because of the windows section. But design B has the 3 fins - which are very unique and important for the Crossfire. So my favorite would be the windows of design C but with the fins on the fender of design B. Maybe this is possible from a designers view - i'm not a designer.
Rear view: I like B most, but have to say that C also is also sexy and maybe a little more modern. C is more unique.
To me it would also be very important to have an outstanding interior design. I think that is a lack of the production Crossfire car design. I don't know what are the possibilites in a "kit car" like the Factory Five Daytona Coupe. But personally i would like to have a well designed interior.
I've done the survey, but wanted to tell you more detailled aspects here. Hope that's o.k.
Regards
Markus
PS: Added a sideview. I know it's not perfect, because of the proportions. As said before, i'm not a designer.
