The 1942 Super coupes adopted the appealing Sedanet fastback style that had been the sensation of 1941 on Century and Special. New wider and lower bodies were offered and "Airfoil" front fenders that flowed into the lines of the rear fenders were introduced on convertibles and sedanet models. The Super had new front fender trim featuring parallel chrome strips. Also featured for 1942 was a handsome new grille with a lower outline and thin vertical strips. A feature shared with other Buicks was a new interior air intake positioned near the front center grille that eliminated the old cowl-level ventilator. The number of body styles was reduced to three with the elimination of the one year only Business coupe
