Well I have a couple of scenario lineups written down. Both start with the '01 Acura Integra Type R. After that it gets fuzzy until I can test them on the track.
But choices include the Audi Rally car thing that Tez chose for me, the Audi R8 LMS dealio, RS200, RX-8 Type S, an HSV race car, an NSX Race car and something else. I'll probably find out half of them suck and change it on race day...
