Good news for GM, but here's a question for Americans! (which takes us off topic)
Why, when you ask a Canadian, we are proud to say we drive American vehicles? Most of us attribute being American as "North American" i guess, because we aren't actual statesiders. Which, guess what? Also includes Mexico!
So when i say domestic, it is built in the borders of Canada, USA, and Mexico. That's North America, THAT's American made, THAT's domestic automobiles. It didn't leave a continent to cross a large water body to get over here, and the head office is HERE.
