IMO, if it's built here in the States.. it's a domestic car. In order to be an 'import" it must obviously be imported. Just about all automobile manufacturers build cars globally. That is why the "Support USA - buy American' slogan is dated and shows the true ignorance of anyone who still preaches it.

100% of the profits do not go back to Japan, Korea, or anywhere else in the world that has an automobile industry. Portions go back into the assembly plant where it was built (wherever that might be) the designers/engineers who created it, the suppliers and the majority of the rest goes to the shareholders. If Japan gets any, it's a very minute percentage.
