Tailfins soon lost popularity. By the late 1950s, Cadillac and Chrysler – driven by the respective competing visions of GM's Earl and Chrysler's Exner – had escalated the size of fins till some thought they were stylistically questionable and they became a symbol of American excess in the early 1960s. The 1961 models are considered the last of the "Forward Look" designs; Exner later referred to the finless 1962 downsized Plymouth and Dodge models as "plucked chickens". He believed Chrysler executives had "picked" away at the cars to make them lower in cost.
