yes i believe that is what taka did but it was jacksonville port not tampa i think. the silvias got sent off along time ago. he reads this board sometimes but you'd be better off finding him on wanganmidnight.com's boards he posts there recently.
i know there are various people in miami and stuff who have imported cars somehow for longer than a year, a few of them are caribbean guys who have contacts in jamaica, puerto rico, and areas down there that are somewhat parts of the US or easier to import from as far as cars go.
i know al and patrick at garage advance got a few cars imported but i dont know if they'll be able to keep them longer than a year but its a start maybe. they imported a Honda Beat i think, one of those minibox cars (like an echo) and they are bringing some soarers and skylines and silvias over. he might be able to help, other than that i know not much of anything besides cali people.
also some guy on honda tech i think bought an r33 skyline and actually had it legalized but he lives in utah or nevada or something and apparently it was way easy to legalize, florida might be harder.
