While Ford continued to refine the manufacturing process to reduce cost, Sloan was inventing new ways of managing a complex worldwide organization, while paying special attention to consumer demands. Car buyers no longer wanted the cheapest and most basic model; they wanted style, power, and prestige, which GM offered them. Sloan did not neglect cost, by any means; when it was proposed Chevrolet should introduce safety glass, he opposed it because it threatened profits. Thanks to consumer financing "via" GMAC (founded 1919), easy monthly payments allowed far more people to buy GM cars than Ford, as Henry Ford was opposed to credit on moral principles. (Nevertheless, Ford did offer similar credit arrangements with the introduction of the Model A in the late 1920s but Ford Credit did not exist until 1959.)
