This is why you take advantage of the Club Permit.

Pay $180odd per year rego, drive it 100+ days a year (cant remember exact days), join a club, attend at least one club event.

Your car needs to be of a good standard and worthy of being in a club event or show and shine, it does not have to be a full blown show car with polished everything but to a good standard where people will be interested in it.

Its not abusing the system, you guys don't know how lucky you are to have it and its a great opportunity to bring car enthusiast together and show the government that just because you have a modified car doesn't make you a hoon. Making you pay ridiculous amounts of money on engineering is the government abusing their power. However your car will be looked at by a scrutineer from a club, it will have to be roadworthy and no crazy modification, im sure an A series turbo will pass easy.
