For the first time, a four-door sedan was offered in addition to the two-door convertible, two-door sedan, and hardtop coupe. Specials and Special Deluxes only came in pillared coupe versions. All Skylarks would have higher levels of exterior and interior trim than the Special and Special Deluxe from which they were derived. The sedan would come with cloth-and-vinyl seats standard, with an all-vinyl interior optional. All-vinyl bucket seats were standard on the convertible and optional on the hardtop coupe. The Skylark Coupe had a lower, more road-hugging profile than the other models. Buick's traditional VentiPorts were integrated into the front half rub strip that ran the entire length of the vehicle, with later versions appearing vertically stacked as on the Buick Wildcat.
