1965 Buick GS

General Overview

With the success of the GTO, Buick finally decided to jump into the muscle car market and offered up an optional package to the Skylark—the Gran Sport.

GM regulated engine size to no more than 400ci, but Buick stuffed the 401ci “Wildcat 445” (due to its torque rating) into their Skylark. To identify the Gran Sport, one must look for a red-filled Gran Sport badge on the grille, deck, and roof quarters on the 2-door coupe and sport coupe, and rear fenders on the convertible. Wheels on the GS were also larger at 7.75×14”.
