The 1953 Buick Skylark was a limited production luxury convertible produced in commemoration of Buick's 50th anniversary. It was based on the model 76C Roadmaster convertible and included all of the Roadmaster's standard equipment, plus additional features including power windows, power brakes, full carpeting, and a "Selectronic" AM radio. The Skylark was powered by Buick's new 322 ci Nailhead V8 engine paired with an automatic two-speed Dynaflow transmission.
The 1953 Skylark was handmade in many respects. Only stampings for the hood, trunk lid, and a portion of the convertible tub were shared with the Roadmaster and Super convertibles. All Skylark tubs were finished with various amounts of lead filler. The inner doors were made by cutting the 2-door Roadmaster's in two then welding the pieces back together at an angle to produce the rakish door dip. An overall more streamlined look was reinforced by cutting the windshield almost 3 inches (7.6 cm) shorter and lowering the side windows and convertible top frame proportionately. Seat frames and steering column were then dropped to provide proper headroom and driving position. Authentic wire wheels were produced by Kelsey-Hayes, chromed everywhere except the plated and painted "Skylark" center emblem.
