4. 2014 Ford F-150
Assembled: Dearborn, Mich., and Kansas City, Mo.
Percentage made In U.S.: 75%
Considering that it's been the best-selling truck and best-selling vehicle period for decades, it's a wonder that the F-150 is still this far down the list. The truck that's been carrying Ma and apple pie to the baseball game since 1948 is an American icon, but has the same amount of American parts and production as the Tundra. Still, Ford consistently culls three-quarters of the F-150's material from the U.S. and assembles it here. The same can't always be said for the 66% American-made Ram and the paltry 40% U.S.-built Chevy Silverado and Ram, which are sometimes assembled in Mexico.
