Look again. Most of the "Japanese" cars sold in America are built in America, and largely with American parts. I wrote a report on this about ten years ago, but I can't find what I did with it.
I had an altercation with a guy about driving an "American" truck. He was in a Ford Ranger, and I was in a Nissan Hard Body. He didn't believe me when I pointed out that his truck was made in Mexico and mine was made in Bowling Green, Kentucky. I told him to go look up his VIN and see for himself.
The latest players in the US car market are the Koreans, with Hyundai and Kia. Not too long ago Hyundai announced that they were going to open a US plant and start building cars here.
In fact, about the only car manufacturers that are taking their plants out of the US are The Big Three, who are largely moving to Canada and Mexico. Even so, the way the rules are written, because they're US based corporations this is still considered "domestic" production.
So before you look at the manufacturer's badge and make an assumption you should find out where the vehicle was actually built.
