Nothing is really "cheap" in motorsports.

With the Escort, you can select three styles and three classes in FWD. They all require a fair amount of work to acquire suitable racing bits--they are not "popular"--but are each nice cars.

I still don't know if they corrected the spec line in the ITCS for the 1991 EGT in ITA. It needs to be expanded to years later than only 1991.

The Festiva has its fans, but is even less popular than the Escort. I would select a Fiesta over a Festiva, but that car is quite old and parts location is a real adventure.

The Contour is not very popular, but it could be worth a shot. Since it is a "world car"--a Mondeo--there may be some race bits for it overseas.

Good luck.
