Yeah, they are probably totally legit. They are an export company. The only thing is that once your Skyline arrives in the U.S. it will not be legal. You will have to set it up through an R.I. That would be Motorex. But since it looks like Motorex is going out of business(from what I hear) and no one has stepped up to take their spot.....then I guess the answer is....NO. You can not import one at the moment. That is what I would gather at the moment.
If you read ALL the info on their site then you would see that some of these questions have been asked. I copied this directly off of their web site.
Question : Is it legal to import a Japanese car in my country ?
Answer : We don't know the regulations of other countries. Please ask somebody in your own country.
