On topic: Heaps of lines attend regular track days and drag events, however as has been said, this is Australia (home to the bogan) and the majority of the cars are always going to be of the awesome v8 holden and ford variety.
But the main issue is, a lot of the people who buy skylines either have them as their day to day cars (and don't want to risk something happening to them) or have bought them so they can put a fulleh sik body kit on it and "pull da chicks with their loud subwoofers!!"
I'm sure you'd find a lot of the people on here have been to at least one TNT/Track day though!! Even still; nothing wrong with dyno queens and high hp cars that persue off track events
