all jokes and opinions about ACA/TT's report style aside
your best course of action, if your really for real about this is to contact ACMA with your issue, you could also contact groups for ethical journalism with a complaint. Further it would be in your interest to invite ACA to a SAU meet. I would suggest these "coffee meets"? you guys have. This could be good for two important reasons
one - environment, the environment is good for educated discussion with the journo they send out. also allows you guys to out number the journo so you have more control over the direction of the interview. bigger number may also help to disspell the idea of you as a minority group on the fringe of the larger "hoon" community.
two - geographically, i assume when you guys meet the cars are parked pretty close to each other perhapes 'displaying'
them? i also assume its in a small car park? if it is the way the cars are presented demonstrates that its a pride thing not a err 'full sick burnout' meet up. also if its small car park you have greater control over people coming in and actually doing burnouts as opposed to conducting the interview in a bunnings car park where there is lots of room for people to ruin the interview.
i don't know, i'm tired haha would be interesting to see if you guys can make a splash in the public sphere though
