The big competitors are Holdens (general motors) (Commodores, I think, but not sure) and Ford Falcons. In this case the finish was Holden in first, Ford in second.
In case anyone cares, the rules are you must use a production RWD car with a pushrod 5L v8 and run on normal premium fuel.
That did that to keep the japs out. They dont have pushrod v8'a or sell a RWD family car here.
Before the Supercar series we used to have Group A. The Cosworth, then the godzilla, used to kick the shit out of the Ford and Holdens so all the fans stopped watching.
It's not bad though, the cars are damn near identical so it becomes a 'driver' race, rather than a F1 style 'who has the best car and pitstop' race.
EDIT: On a personal note, what's the deal with your boring as batshit driving in a circle 500 times races?
