Purchased this 2009 Buick Lacrosse in April 2009, after selling my great 2006 LaCrosse to a relative. This new vehicle proved to be as good as my older one. Only reason I bought in 2009 is to get the last of the 3800 engine. Newer engines might have more HP but are no more reliable than this last of a great breed. The vehicle is quite, responsive and very comfortable. My only concern is the fact the battery ran completely down while sitting for 3 days. Dealer found no problem and it has not happened again. Still, there is the concern it might happen when I am a long way from home. The 'antiquated' 4-speed transmission is smooth, responsive and gives as good a mileage as 6-speeds.
Quiteness, smooth acceleration, and comfortable interior. The driver's information center is also great.
Suggest a more comfortable driver's side door panel be developed so ones left arm can rest comfortably on the door, where most men put it when driving.
