mm the only thing is and im not sure about qld but here in vic, you cant have anything thats not standard for instance when i was on my p's (2008) you are not allowed to modify an engine from its original specs so the 6cyl in the vehicle has to remain standard cant change the head manifolds carbie etc nothing that enhances the performance of the vehicle you cant have a turbo or supercharger no injected engines etc, infact the panelvan i am doing up now was my first car i was pulled over driving it, not doing anything wrong but because of the noise it made they pulled me over, and for driving with a 308 i lost 3 of my 5 demerit points and $326 fine i wasn't allowed to move the vehicle from the carpark i had pulled over into, and some people say wellcops dont know what they're looking at and they take the risk (i was one of them) it only takes one cop to get you and thats it my $15000 panelvan had to sit and wait until now
