A mate brought a Harley over from the States and it cost him $5000 all up for shipping from the states to a company in Queensland (I think they are called Geezers, or similar), who did the conversion and then over to him here in WA.
He went over there, bought the bike, rode it road the states for about 3 weeks and then shipped it back.
He reckoned it was worth it cause he bought the bike for US$12,500. Plus the AU$5,000 for the above. Total about 17,500 as the US and Aust dollars were worth about the same at that time. He had priced the same model here and he said they are selling here for about $30,000, so if he didn't like it after all he could sell it and make a profit.
HE DID ALL HIS HOMEWORK BEFORE HE WENT AHEAD WITH THE PURCHASE THOUGH.
