Too expensive. I browse the Okinawa military car forums. GTS-T's are practically given away. Some are literally given away. My cousin knows a few people there, that will probably be the way I do it if I end deciding on it. 1-2k for the car, a couple grand to ship and then all the bs fee's when it's landed.
None are truly legal yet since they were not built until the end of 89'.
I would always be looking out my window if I had "state" legal car. Those cars are just ticking down until someone from a 3 letter agency comes knocking.
I know of 3 Skylines around Athens that have 240SX vin's.
If not's an antique and doesn't have these, stay away.
