Correction. 1953 Chevrolet Bel Air Convertible. Chevy had all new styling for '53, and BelAir became a series instead of the name applied to Chevrolet's Hardtop Convertible first introduced in 1950. In addition to the convertible in the BelAir series, there were two and four door sedans, and the ever popular two-door hardtop. 1953 and 1954 Chevrolets are similar in appearance except for slightly different grille and taillamps.
