The 1959 model year was the most extravagant for the General Motors concern. Body shapes obeyed the fashionable "cosmic" trend, which is still admired today. Bonneville in the Convertible version was the highest-level model of the Pontiac car manufacturer. It has a V8 engine with a displacement of 389 cu.i. (6,364 cm3) and 300 horsepower, which is coupled with an automatic transmission. All windows are electrically operated, as is the retractable roof. Power steering, brake booster. The interior is in the original factory three-color combination. The sound of the engine, as well as driving "without a roof" will infect you with the V8 virus for life.
