If you're keeping your us plates on your car why would you bother?
It only applies for cars that are registered in the Netherlands(correct me if i'm wrong )
If you are planning to sell it over here there are more things that have to be changed as well before you can get a Dutch number plate, the RDW has to check en test your car on the Dutch roadcar standards and thereafter they going to decide how much vehicle tax is still valid on your car.
It might not be benificial to sell the car over here, the tax is spread over a period of time, each year it gets a little bit less but the first years are the most expensive, but as a rule of tumb when a car is older then 3 years it might become profitable to import a car in NL. A Jeep is in NL an expensive car thus you also pay more tax on it
Hope i didn't scare you into visiting cloggyland, its only the government that is unfriendly
