Also, those cars can be easily adapted to work in NFS 4 (High Stakes). You just need to get a small program to convert the VIV file. The steering is a little too stiff compared to the other NFS 4 cars but that can be adjusted. Unfortunely, the damage feature does not work. If anyone wants the NFS 4 version of the Fiero just send me an email (daehkcuf@hotmail.com).
Eventually, I'd like to make a V8 notchback version but that will be dependent on free time.
Also, for anyone want to obtain NFS 3 or NFS 4 then I'd suggest CompUSA. Only $10 each. You can sometimes find hacked versions on Kazaa but they may not work.
