Cars with at least 75 percent domestic content are becoming an endangered species, and for the first time in the American-Made Index’s nine-year history, the list has fewer than 10 cars.

The Toyota Camry took the top spot this year, as 2014’s top vehicle — the Ford F-150 — fell below 75 percent in domestic-parts content with its 2015 model-year redesign. The Toyota Sienna, Honda Odyssey and Chevrolet Corvette return to the list alongside GM’s three-row crossovers: the Chevrolet Traverse, GMC Acadia and Buick Enclave. The Michigan-built SUVs were last on the AMI in 2013.

These cars combine for the vast majority of new-car sales, and U.S. production remains on the rise.
