From 1978 to 1990, the Park Avenue existed in Buick as a trim level within the Electra full-sized car. In 1991, the Park Avenue superseded the Electra brand name to become a luxury sedan. Redesigned in 1997, the Buick Park Avenues sophisticated new look was based on a three-inch wider wheelbase. Engine power for the 1998 vehicle was derived from a 3.8-liter Series II V-6 powerplant generating 205 horsepower. The high-end Park Avenue Ultra included a supercharged version of the V-6 engine producing 240 horsepower. A front-wheel drive sedan, the Park Avenue channels engine power through a four-speed automatic transmission. For 2003, a new front grille as well as a new tri-shield Buick badge was found on the front and rear trunk. The 2003 Buick Park Avenue also included the exterior accentuation of Ventiports on the front quarter panels. The 2003 base model of the Buick flagship sedan included standard 16-inch wheels, automatic climate control, keyless entry and four-wheel disc brakes with anti-lock braking system. Six-passenger seating was found standard inside the Park Avenue with an optional five-passenger setup available. After 2005, Buick consolidated their large car line-up by introducing the Lucerne as a replacement to the Park Avenue as well as the LeSabre. In commemoration of the final year of production, Buick released 3,000 Special Edition models that included standard chrome wheels and some featured a two-tone interior. The Park Avenue was the last Buick to be offered with a hood ornament.
