Question about importing generally

This is not about Skylines. We know the Skyline cannot be imported as a kit car. That has been went over a thousand times. But the Noble112 which is a British production sports car can be disassembled and imported as a kit car. So I was wondering is the Skyline the only car that cannot be imported as a kit car? Before the Skyline was being legalized in the U.S. was that ever done? Besides the Skyline what other cars cannot be imported as a kit car? Can someone clear this up. Thanks.

Wasn't this on Car and Driver TV the other day? I think that it is actually bought as two parts, the engine and driveline, and the body. I don't think it is actually assembled until it arrives in America or wherever it's going to.

Ultima GTR is bought, and imported to the US the same way...

Im not entirely sure why it is different... But I seriously dont feel like getting into it again.
