I don't know why you want to just import another car...Sounds like yours is a good time...
Anyway, to import a car isn't cheap. Of course it all depends on what kind of a shipping company you use. I know from research and experiences in wanting to import a car from Japan, it could cost upwards of 5 or 6 grand in American (for a Nissan Skyline

) It may be different because that seems to be a lot longer of a distance than Japan-California, but its something that you would probably have to make some calls for or do some internet searching aside from this forum...
