Series 60 Special

The Cadillac Series 60 Special ('Sixty Special') was a senior Cadillac sedan built from 1938 through the 1970s. Bill Mitchell's 1938 design pioneered the modern long-low-and-wide American luxury formula, with thin pillars, no running boards, and a lowered roofline. Postwar Sixty Specials continued as Cadillac's prestige full-size sedan.
