I purchased mine through Unusual Auto. He basically functions as a broker and I had mine shipped to Long Beach from Japan. I the had it shipped to Colorado. He provided all the import paperwork, EPA stuff, etc.
I'm in the process of licensing it now, which has beeen entertaining and requires a great deal of patience and acceptance of fees, forms and all thing government. It's moving along though.
If you decide to import one, feel free to hit me up with questions. I've learned a lot so far and I'm happy to share. I've had good and bad experiences with this process but the one thing to keep in mind is that if you go through a broker you are going to have to do quite a bit of work yourself. The other way to go is with one of the "dealers" that import them and title them. You will pay double but they are doing all the leg work and paperwork for you so that may be worth it. They also generally do a mechanical overview and sometimes timing belt, etc.
I wanted to learn the process so I went the cheap route. Ask me again in a month if that was a good decision.
