During this period (and into the 30s), Sloan and his team established the practice of targeting each of GM's automotive divisions to a specific demographically and socio-economically identifiable market segment. Despite some shared components, each marque distinguished itself from its stablemates with unique styling and technology. The shared components and common corporate management created substantial economies of scale, while the distinctions between the divisions created (in the words of GM President Sloan) a "ladder of success", with an entry-level buyer starting out at the bottom with the "basic transportation" Chevrolet, then rising through Pontiac, Oldsmobile, Buick, and ultimately to Cadillac.
