In Australia there is a 5% import duty, 10% GST (Goods and Services Tax or VAT) and 33% luxury car tax for the amount above about $60,000.
Jay has been doing demos to Roadster buyers in a Roadster Sport in which case the $200,000 figure looks about right.
Due to the small market they may only be importing Sports, if it is for a standard roadster however, thats another matter.
I'll ask him tomorrow at the event.
