That F100 looks sharp!
If you're considering other cars to cast, I have two favorites...............
The first is the Porsche 550 coupe (it ran the La Carrera Panamericana, in fact it won it!):

The second is an OSCA (what was left of the Maserati brothers after they sold their original company to Orsini). This MT-4 ran Sebring and won:

Takes you in a different direction, but I think they're both great looking cars!
