If youre in Perth, give Jshop a call 9358 4969 and speak to Raheem. He's a broker as well but goes to Japan like once a month/2months to source for cars/parts coz he says he can do compression test...etc and he has all these USS ID cards.
The only problem is that he sells a lot to Dealers only and only sometimes brings cars to sell to the public.
Just to add some additional info. Shop around (my advise).
