if the start price around 3700000yen,more than likely it will up to 5000000yen+fob.
my mate just import one R34GTR(not V-spec),he paid 4850000yen FOB(white)
i think you need looking around 5000000yen for the good R34GTR.
if you looking for V-spec2 or M-spec.i think you need have spare 6000000yen+FOB.
5000000yen= AUD60000 x20% tax x luxury tax+shpping.it will cost $85000 landed etc.
very expensive.
