About the 2009 Buick LaCrosse

1st generation (2005-2009), final year before the all-new 2010 redesign.

Buick positions the LaCrosse as a quiet, comfort-first midsize sedan with more upscale touches than a typical family car. The pitch centers on a hushed cabin, easy controls, a smooth highway ride, and familiar Buick styling cues like the waterfall grille. In 2009, the LaCrosse is less about sharp handling and more about relaxed daily driving, long-trip comfort, and traditional sedan features such as dual-zone climate control, remote start, and an available six-passenger layout on the V6 trims.

The CX is the comfort-focused version, with a quiet cabin, remote start, dual-zone climate control, and a 3.8-liter V6. The CXL adds leather seating and heated front seats, while the Super stands apart with a 300-hp V8, firmer suspension, stability control, and upgraded audio.
