The Chevy is one of the most popular classic cars on the road today, but why General Motors wanted to build an all new line of Chevrolets for 1957 from the ground up but manufacturing problems stymied the process. Ed Cole, the head engineer, had no choice but to reuse the chassis, suspension and most of the drivetrain from the previous year. Having only the body styling and options to work with, Cole oversaw the creation of an all new dashboard, cowling, chrome trimmed headlight pods and the now-famous rear fins. He also lowered the car by using fourteen rather than fifteen inch diameter wheels and the front grill was redesigned to make the car appear wider.
