Which automaker do you think is the most "American"? Some might say Chevrolet, since they're the self-proclaimed Heartbeat of America. Others might say Ford since the Mustang is as iconic an American image as baseball and apple pie. What if we told you the answer might just be Hyundai? As of next year, 80 percent of the vehicles that Hyundai sells in the United States will be made here as well.
