Well if you go through a company here I am sure they do that and get the best car for your "money"
should have a look on car sales, trading post, car point websites and see what R33 GTS are around in melbourne...and buy a Navman he will tell you how to get around..
You would know your way around Mel in a month no probs..It didnt take me long to know my way around Sydney
I would just way up all your options ..It might be cheaper to buy one that's already here...Plus I like to see what I am getting before I buy it..But that's just me
