Depends on the country---
Import duties and taxation are probably lower in the U.S. than in a lot of places.
I know a fellow in Thailand that bought a new Ford GT for $165,000 from the US., and by the time he got it shipped, registered and ready to go, it cost him about $600,000 because of duties based off the size of the engine, etc.
It's also a LH drive car in a RH drive country. He must have really wanted it!
