The Ford Focus ST is in GT5, and it's sort of a successor. In any case, the Renault 5 Turbo (1980?) and Peugeot 205 Turbo 16 (1985?) are somewhat similar in concept. I have both but unfortunately they're not on the market right now!
In any case, both the Renault and the Peugeot are in the Online Dealership as I write this. If you still want to trade I'm sure plenty of people have them.
EDIT: Ah yes, how could I forget the Lancia. That and the Focus are premiums and not at all expensive when you consider the easy money available in seasonals right now.
