You can do a search here on grey market cars and see the previous discussions that have been done on this topic.
If you manage to get the car into the US, then you would have problems trying to find a mechanic to work on it. Also, you will probably not be able to ever resell it either. Overall, I do not think it would be worth the long term hassle.
