Buick Lucerne

The Buick Lucerne was a full-size upscale sedan sold by the Buick division of General Motors from 2006 to 2011. Introduced at the 2005 Chicago Auto Show, the Lucerne replaced both the Park Avenue and the LeSabre for the 2006 model year. Based on a revised G platform, it served as Buick's flagship until replaced by the second generation Buick LaCrosse.
