Buying a Car in DR

I'm looking for information on car dealers (used or new). Do you know how to get web pages addresses from dominican car dealers? I tried almost all of the DR's web pages that I know of. I'll be moving there only for a few years and I'm considering the options of taking my car over there, or buying one when I get there. I understand that customs are very slow and expensive, and you have to "mojar la mano" a lot, and the paper work it's a never ending story. If someone has entered a car lately thru a dominican port from USA, I'd really apreciate your input. Thanks in advance. Nancy
