Ford's F-150 pickup has earned the No. 1 spot on Cars.com's American-Made Index, which is compiled based on where the cars are assembled and how many of the vehicle's components are domestic-made.

Now in its ninth year, the American-Made Index is based on the percentage of U.S. and Canadian parts used in the vehicle. Despite coming from a Japanese carmaker, the Toyota Camry came in at second place because the car is at U.S. plants and built with mostly American-made parts, USA TODAY reported.

Because of the American Automobile Labeling Act, Canada is included in the "domestic" designation. Where a car is assembled and what percentage of its parts is domestic-made are both shown on the window stickers of every new vehicle.

General Motors' Buick Enclave, Chevrolet Traverse and GMC Acadia crossovers came next on the list. The Dearborn, Mich.-manufactured Ford F-150 came in first for the second year in a row, while the Chevrolet Corvette, Honda Ridgeline, Honda Crosstour and Dodge SRT Viper were newcomers on the 2014 list.

The Dodge Avenger sedan, which came in third place on last year's index, was disqualified for the 2014 model year list because it has no designated successor and may be discontinued soon.

Just 10 cars were eligible for this year's list, making room for the four models that made the index for the first time. The 2014 list marks the smallest number of cars eligible for the index in its history. The previous model year, 14 cars met the mark of having domestic-made parts of 75 percent or higher, while 20 cars were eligible in 2012 and 30 the year prior.

"This consistent decline points to global nature of cars these days," Patrick Olsen, Cars.com editor-in-chief, said in a statement. "Production in the U.S. is up, but parts are coming from all over the world, making the notion of classifying cars as 'American' more difficult than ever."
