The Bonneville for 1966 was easily identified by the long, wide rocker panel moldings between the fender wells. Bonneville lettering was found on the grille and on the front fenders behind the wheel opening. The standard-equipped fender skirts gave a low and sleek look to the 124″ wheelbase. Body styles available were a 2-door hardtop coupe, 4-door hardtop sedan, a convertible and station wagon. The Brougham option added ID badges to the roof pillars, as well as an upholstery pattern specifically assigned to the Brougham package and a Cordova top could be added as an option. The engine offered was the 389 cid at either 325 or 333 hp depending on carburetion and transmission configuration.
