The 25 year mark for the states starts on the year it was build, not the year of the model. After 21 years the cars are exempt for EPA but needs to be 25 for DOD. If you ship it as a kit car you can't drive it much, and has to pass all these safety tests. If your moving to California smog is a lot more stricter then other areas ie. Texas where you can run straight pipes. You have to get a new VIN number for the car if your registering it as a kit car. Doing that insurance won't cover it properly. In California one of the things you have to do is take it to the highway patrol to get it identified. If you don't have any good friends in the CHP business then most likely they'll report it as a Supra (unless the tard doesn't know the type of car). I don't know how it is in other states, I'm speaking in a California point I'm sure other areas it's more lenient. I have a friend that bought two c10 Skylines from Mexico and registered them as a 240sx insurance isn't at its fullest, but it is possible shipping it to the states. Once the 25 year mark hits though registering it legally is a lot easier. If you'r planning on taking it to the states, I advise you to keep the body as stock as possible. Body kits and such aren't that attractive anymore, unless you find a teenager.
