Further to my previous post I have been able to clarify the costs of importing
Presuming that have purchased a pre ‘77 Ford Mustang for $9,000 US ( about A$10,000) which should enable you to purchase a car in good running order needing only minimal work for local registration. craigslist.com (LosAngeles) and ebay usa had many suitable cars valued at lest than $9000, some restoration projects for as little as $2000.
A good quality Ford Ranchero ute could be purchased for considerably less and would be the ultimate "tradies" toy.
Presuming exchange rate A$1=90c US
Purchase price $10,000A
US Customs Fee $ 137.50A (approx)
Freight $ 2,500A
Insurance $ 150A (approx)
Subtotal $12,787.50
GST $1,287
Dotars fee $ 50
Our fee 5% $ 500
Pre purchase inspection (if required) $ 150 (approx)
Total $14,774.505
Depending on condition of car and requirements I have been quoted between $300 and $1000 to get blue slip, will depend to some extent on age of car.
Compare what you can buy locally with an import. Hope this will assist
