wow! i wasn't expecting to see race cars like that! that would have been interesting to see on the track with a miata or like a mazda3 lol.
Without knowing much about the sport, I'd guess that that was a Mazda Cup car, not a Formula 1 race car. Much less expensive to own, but still ridiculously fast and hugely awesome.
There was an episode of Top Gear where Richard Hammond attempts to drive a formula 1 car. After seeing it, I didn't feel so bad that I'd never in my life have the opportunity to drive one of those machines. I would however love the chance to drive a car like #64, mentioned above.
