CHICAGO, June 30 /PRNewswire/ -- As more foreign auto manufacturers open assembly plants in the U.S., the notion of "buying American" has taken on new meaning. With the 4th of July Holiday upon us, Cars.com has created the American Made Index to help consumers identify the top ten vehicles that are truly the most American in terms of their parts, where they're produced and that are popular with U.S. buyers. As expected, many traditional American manufacturers have made the top ten; however, several Toyota vehicles including the Toyota Camry, Camry Solara and the Siena also made the top ten.
