Find out for real.
That's an interactive map of all the major brands sold IN the U.S. and a listing of not only where the engine was made and where the transmission was made but where final assembly of the vehicle is and if the it's made by unionized labor. Pretty interesting stuff.
Granted, some of the models are brand spankin' new but most on the list have been being built in those locations for the last 3-5 years and most of the plants have been in operation longer.
Don't forget to scroll all the way down and see the lists at the bottom for what is assembled in Mexico and Canada too.
