Under company president Alfred P. Sloan, General Motors offered "a car for every purse and purpose." A buyer might start with a Chevrolet and gradually trade up to a fancier Oldsmobile, Buick, or Cadillac. It was the opposite of Henry Ford's one-size-fits-all Model T. As customers' wants and wallets grew in the 1920s, Sloan's approach took hold throughout the industry.
