you may want to go down the personal import way as the rules are somewhat less restrictive regarding modifications if you reallly want to hang onto it, can give you some emails of a few guys that have recently imported cars here to give you an idea, what year is your cossie?? as i know anything after 89 creates problems but i got my 90 4x4 saph in from new zealand as a personal import, as for the rs scene in aus it is thriving just a greater distance to go for meets but that's where the fun feel free to pm if you have any questions
