The 2005 Buick Park Avenue, a full-size luxury sedan, marked the end of an era for this model line. Introduced in 1991 as a replacement for the Buick Electra, the Park Avenue carved its own niche in the luxury sedan market by offering a comfortable and refined driving experience coupled with a spacious interior and a generous list of standard features. The 2005 model year inherited the design and styling introduced with the 2000 redesign, featuring a conservative yet elegant exterior with a large chrome grille, swept-back headlights, and a long, flowing profile. Inside, the Park Avenue provided luxurious accommodations with plush leather seats, wood accents, and a generous amount of legroom and headroom for both front and rear passengers. The 2005 model offered a choice between two engine options: a 3.8-liter V6 generating 205 horsepower or a 4.6-liter Northstar V8 producing 275 horsepower, both mated to a four-speed automatic transmission. Despite the availability of the powerful V8, the Park Avenue was not known for its sporty performance but prioritized a smooth and comfortable ride, a hallmark of Buick vehicles.

The 2005 Buick Park Avenue provided a complete package of luxury features, including standard amenities like power windows, locks, and mirrors, automatic climate control, cruise control, an AM/FM stereo with a CD player, and a comprehensive suite of safety features like dual front airbags, side airbags, and anti-lock brakes. Optional features offered by Buick included leather upholstery, a sunroof, heated seats, a premium Bose sound system, and navigation. While the Park Avenue was a well-regarded and comfortable sedan offering a blend of luxury and practicality, it faced stiff competition from other established players in the luxury market, leading to its discontinuation after the 2005 model year. The 2005 Buick Park Avenue served as a final farewell to a nameplate that had successfully established itself as a symbol of comfort, refinement, and value for over a decade.
