Cars.com's American-Made Index measures cars built and bought here, with high domestic-parts content as measured by Congress' 1992 American Automobile Labeling Act. But with each passing year, the number of qualifying models dwindles, and at some point soon, the AMI may have fewer than 10 cars left in it.
For the 2013 model year, just 14 models had domestic-parts content above 75%, according to the National Highway Traffic Safety Administration. In the 2012 model year, 20 cars met that threshold; in 2011, it was 30. Past AMI regulars like the Honda Accord and Chevrolet Malibu have tumbled below 75% domestic content; the Ford Explorer, which ranked in fourth place for the 2011 American-Made Index, has just 50% domestic content today.
Kristin Dziczek, who directs the Labor and Industry Group at Michigan's Center for Automotive Research, calls it the "global car" effect, where shoppers from Denver to Dubai see the same model in their showrooms.
