GM announced on February 8, 2005, that the Bonneville would be dropped from Pontiac's lineup for 2006. The last Bonneville left the assembly line on May 27, 2005. Only about 12,000 Bonnevilles were sold in 2005. With more than half of Pontiac dealers also selling Buick models, the Buick Lucerne (along with the Chevrolet Impala and Pontiac Grand Prix) continued as GM's only mainstream full-size cars until the introduction of the 2008 G8.
