Thanks for the excellent information. I've thought about this for a while now; what if the vehicle was sent to either Canada or Mexico, then brought into the states? I imagine the same rules apply, but I'm not positive.
It would definitely be worth it to disassemble the car and send it in pieces over a matter of a few weeks in order to get it here. Whether the DOT considers it a kit car or not is irrelevant, you'd still own a street legal Skyline. As for the list of parts you'd have to take off before shipment, is there anything from stopping them from entering the country afterwards? Then you'd be able to throw them on afterwards. Just a thought. Any information would help.
