Depends on the car itself. If you need to find a good service. I can suggest to contact this reliable company clearitusa.com/customs-consulting where is possible to order any importing service, to deal with all the documents. These guys are dealing with all the documents and to check the car during the whole travel to the destination point.
Duty is 2.5% of the transaction value; there is a merchandise processing fee that caps at $485, and a Harbor Maintenance Fee assessed on cargo entering by sea at harbors maintained by the U.S. Army Corps of Engineers. That is all the government charges you to import. The car must meet EPA and DOT standards, of course. If not, you have to pay to bring it into compliance, if that is even possible. Finally, you will most likely choose to pay a customhouse broker to handle the paperwork (although nowadays it is almost all electronic).
