We do have a 30% luxury car tax that applies to the wholesale value over 57K plus a VAT of 10% but that goes nowhere near explaing the difference in price of these cars between the US and Australia (over double even allowing for our slightly lower dollar). Try it for youself on the Porsche.com.au website (build your car) and use postcode 2000 for example (but we are getting off thread!). I suspect there is a limited number of cars (RHD) the importer can get so they price them to what the market will bear.
