I'm not gonna read 38 pages, so if I repeat anything, I am sorry
What I'd like is...
FZ5 roadster (optional like the UF has)
RB4 GTR (500bhp to even the odds against the FZR too)
LeMans Prototype car (Toyota GT-One as a base maybe?)
A 4WD Wagon (200bhp, maybe based on the FXO?)
XR GTS (350bhp version of the XRT, a contender to the FZ5 and RA)
UF1300 (think Mini Cooper S)
UF500 (Even slower than the UF1000, but would be perfect as a AutoX car)
XF Turbo (180bhp, not in the TBO class but higher than the XFG/XRG class)
And something for the oval'ers
FXO NASCAR (NASCAR fans can fill in the spec sheet)
