High Quality Content by WIKIPEDIA articles! The AMC AMX is a two-seat GT in style and approach sports car that was produced by American Motors Corporation for the 1968 through 1970 model years. The AMX was also classified as a muscle car, but "unique among other American cars at the time due its short wheelbase". The AMX was also the only American-built steel-bodied two-seater of its time, with the 1955-1957 Ford Thunderbird being the last ones. To a degree, the AMX was a competitor with America`s only other two-seater of the era, the Chevrolet Corvette for substantially less money. With a one-inch (2.5 cm) shorter wheelbase than the Chevrolet`s 2-seater, "the AMX was often seen by the press as a Corvette competitor."
