2006 Buick LaCrosse Rear

Following the update of Pontiac's Grand Prix by a year, the Buick platform-mate formerly known as Regal got a new look and a new name in 2005. The pushrod V6, 4-speed automatic, and much of the redesign carried over. The CXS model has a much more modern DOHC V6 with 240, but otherwise, most of the Regal is status quo.
