The 2005 LaCrosse is a much better car than my previous 1997 Buick Regal. Handles and rides much better and doesn't have that old Buick float. It feels more like a sport sedan. Fit and finish is also improved and it is quite quiet. I think the old 3.8 V6 has been improved. Smoother and quiter. The gas mileage is still a downer. It gets 30 on the highway, but only 17-18 around town. Overall, its a much improved car.
