Ok, first off, a Canada legal Skyline does not make it US legal. It is still a non-conforming vehicle in the US. It needs as RI assigned VIN number once conformed, something a Canada import does not have. Stating that the vehicle is registration ready for the US is BS and close to being illegal.
This is the import process from Canada:

Try to get the required letters from Nissan, but they will not provide them.
That means that the Skyline would have to be imported by the normal Gray Market rules the have to follow if they come from Japan:

Which all goes back to Motorex. Who isn't legalizing them right now.
If you're an honest seller, you'll warn US people of the requirements, there by taking any chance of being accused of fruad away from you.
If you're just looking to keep with what you've said, that the car is "registration ready for the US," and sell it to some sucker in the US to make a lot of money... Then disregard what I said.
