This applies to almost everything, not just automotive parts. Also take a look at just for example, the price of a new Subaru STI in USA is low 30k, here its above $60k. The dollar is close enough to even, and the car is manufactured in Japan. That is a huge difference. Even more so, check the price of a new 911. Around 240k here and 80k in the USA, once again its not made in the US. But this applies to a lot of things, we earn more in Aus and are willing to pay more for a product would be part reason.
