I shipped my '72 Pantera from NYC to France, and three years later shipped it from France to California. I can tell you all about the SHIPPING process, but can tell you little about the IMPORTATION process, since I ran it on US plates the whole time it was in Europe.
Drop me a PM and I'll give you all the details. Summary - shipping the car was far easier and far less expensive than I thought it would be. I shipped my Pantera in '98 or '99 and it cost me $750, including all taxes, fees, and insurance. France to CA was a little more expensive - roughly $1100 in 2002.
The major shipping companies won't deal with people like you and me - you need a broker. My broker, who has since retired, did a nice job of handling all the paperwork.
My car went on a RORO, a roll-on, roll-off. Basically a big ferry. It is the method used by all the car manufacturers to transport their cars across the ocean. The cars go sealed in the hold, just like crossing the English Channel.
