2006 Buick Lucerne CXL V6 4dr Sedan (3.8L 6cyl 4A)
On a recent 2200 mi trip I really enjoyed my drive. I drove the entire trip by myself. I did find that the seats were comfortable and the heated seat helped with fatigue even in July. Avg about 29 mpg at 75 - 80 mph. There was a problem with the AC dripping condensation on my left foot.
Better paint jobs. Front window post a little narrow so that you don't have such a large blind spot
