Welcome,
There is a good 73 Cuda in Brisbane for $43K right now I saw advertised on Mopar Market, I bought my Cuda out of Melbourne,, yes you can buy from the US and that is what I had intended on doing, that said, my car came up, I did the exchange rate conversion, took 10K off (this is pretty much what you need to budget to import by the time you pay shipping to exit port, cleaning, shipping to Au, customs fee's, duties, quarantine (if its slightly dirty) and so on. Then what you have is the US$ cost of a local car if it was sitting in the US, you can also easily have a look at it rather than take someones word for it etc.
