Yeah I did notice that Conrad, the rain tyres appeared every time the car was on gravel! Same in the race at Bay Park. Millen did actually win both races at Bay Park, and it was a wet/dry meeting. I guess thats why it kept switching from wet to dry etc. The in-car footage at Bay Park was obviously staged, as Millen was just blowing by other cars on the straights. I assume this must have been filmed during lunch break or something at the event, because the crowds were all there?

I saw a Roger Donaldson doco several years ago in which Millen was interviewed about Smash Palace. He said when he tracked down the Ralt, he had to get someone else to go buy the car for him, otherwise the seller might have suddenly increased the price on learning who the buyer was.
