V8 Supercars...... great for the game, 680hp sedans Holden and Ford. They have a few classes so u could offer a demo, S1 & S2 version. And Bathurst is a track to consider as it would have to be the most challenging circut for GT cars, with the use of the 7L V8 Holden Monaro.... Australia have some great cars that can put a Porche to shame!
