I am under the impression that the Dutch are more relaxed comparing to the german situation where each change needs to be approved by TUV and added to the registration papers.
There are a lot of companies specializing in importing new and second hand cars into the Netherlands. With a favourable exchange rate and cars generally being much cheaper in the US this is a good business model. You could contact one of those companies and ask them to arrange everything. Alternatively you could handle things yourself. In that case it would be wise to contact the RDW, in these days I hear they are becoming quite service oriented. This link contains some info on the proces and requirements.
