Chevrolet saw record car sales in their 3 year run of 55, 56, and 57 with the most popular year being 1957. Three distinctly different models were offered this year: the One Fifty Series 1500, the Two Ten Series 2100 and the top of the line Bel Air Series 2400C. Some minor stylistic changes would be created and a wide variety of models and options would become available. These changes included a new oval shaped front bumper/grille combination with torpedo style bumper guards. This new front end was highlighted with the famous Chevrolet bowtie being placed in the center of the grille with a horizontal bar. The hood would have parallel bulges with bullet shaped ornaments. New side moldings were introduced in 1957 and were distinctly different with each series in 1957 – being more elaborate on the Bel Air than the One Fifty. One of the notable new features for the 1957 models was the rear fenders which were reshaped to incorporate broad, flat tailfins.
