The Ford Mustang is an American car manufactured by the Ford Motor Company. It was originally based on the Ford Falcon, a mid-size car introduced in the United States in 1959. The Mustang's styling, performance, and affordability made it an instant hit and early Mustangs remain highly sought after by collectors and enthusiasts. The Mustang is credited with popularizing the "pony car" class of American muscle cars, a description given to affordable, sporty coupes that feature long hoods and short rear decks.
