From when I brought in my Factory Five, I recall talking with customs and really they only want to let in complete registered cars with VIN numbers, or car parts.

If you are building a car and maybe not quite finished yet, if you ship it with most of the car in one box, and the engine, gearbox, wheels say in another box, they would consider that car parts and let it in. If all together in one box, then its called a car, so it has more restrictions on it.

You could even finish the car then pull the engine out for shipping and it should be ok.

Then complete and do final registration here. My FF is registered (several in WA) so we know they pass.
