I was going it at it from the tack that you fab together an "Assembled from parts" car (or just say, the frame and use the rest of the parts from donor cars) and register it 100% legal, why not use 100% parts from a foriegn car? Didn't see any restrictions on those on the registratation form, and I don't think (here's where I could be off) it's a problem to import the parts themselves. I'm not going it at is as "dissassembled and reassblembed imported car" but as "assebled from parts car that happens to use lots of foriegn parts". Those people who do own Skylines have to get spare parts from somewhere, and any other car in the world could hypothetically be here and need replacements, since there are exceptions to the import restrictions. If you're a foriegner coming here for a year, a military or other US Gov'ment serviceperson returning from abroad (again, 1 year cap on the car being here), if it's for track racing (has to be stripped of things that make it roadworthy, like a reverse gear), or for research, any foriegn car is a go.
