GM styling as a whole lost its frontrunner status in 1957 when Chrysler introduced Virgil Exner's "Forward Look" designs. When compared side to side, Oldsmobile looked dated next to its price-point competitor DeSoto. Compounding the problem for Oldsmobile and Buick was a styling mistake which GM called the "Strato Roof". Both makes had models which contained the heavily framed rear window, but Detroit had been working with large curved backlights for almost a decade - consumers disliked the roof and its blind spots, forcing GM to rush a redesign into production on some of its models.
