Can I ship a brand new car overseas or its illegal by any law or manufacturer policies?

I'm planning to by a brand new car from Ford dealership in the US and planning to immediately ship it overseas to Saudi Arabia (it will be fully paid in cash). I heard that there are some issues and maybe its prohibited to ship a new car unless it's been in the US for six month! Has anyone hear of this before or been in the same shoe?

Yes.
The selling dealer can get into big trouble with Ford. This was due to the enormous demand for the "new" Mustang.
GM had the same policy regarding the Camaro when it was new.

But what do you care… You buy the car.pay your taxes and then ship it wherever you want to. If the dealer gets in trouble.so what

No, it's completely legal and okay on your part. I bought an Audi a7 from new York and shipped it to jordan. I didn't import the car to jordan though. I just kept my new York plates. Anyways its better and will make your car stand out from the rest.
