This nameplate began as Buick’s premium Park Avenue trim on the Electra and then became a standalone full-size sedan for the 1991 model year, when Buick retired the Electra name in North America. The first U.S. run continued through the 2005 model year and positioned the car as Buick’s flagship traditional sedan, emphasizing quiet comfort, generous space, and a distinctly upscale American luxury character. During that era, the car evolved through major updates rather than constant reinvention, with the later cars carrying Buick’s familiar smooth-road demeanor into the final years of the large front-wheel-drive sedan format.
After the North American version ended, the nameplate returned in a separate production period for China, where Buick used the Park Avenue name on a larger premium sedan built for that market starting in 2007. That Chinese-era car was a different vehicle and market proposition, reflecting Buick’s expanding role in China and its strategy of adapting historic Buick names for local buyers. Production of the Chinese Park Avenue ended in 2012.
Because the nameplate was discontinued and later revived in a distinct market, it is best understood as a Buick luxury sedan nameplate with two separate historical production periods rather than one continuous run.
