I have a black FD
and a dark green ( looks black ) Cosmo.
As far as i know, the only FD you can take back to the states would be a LHD one. The Registered importers do not count the RHD FD as "substantially similar" to a LHD version. And once they know it is RHD, most dont want to deal with them. Just a few more years and you can bring back FC's and Cosmos.
2011 you can bring back 1986 and older cars with out any problems.
