Purchased the car with 76k. Ergonomics and controls are lame for such an expensive car, but still lots of used car for the money. I have driven about 1500 miles so far. This car is no sports car, but for a large sedan, power is ample (205 hp) and handling seems secure. In my mid 30's and it has surprised me how much people have commented to me that I bought an old people car. Buick has a serious image problem. Neverthless, I prefer to drive something different from the typical rat racer.
Smooth ride and powertrain, good safety ratings, lots of room for people and stuff for a sedan, excellent fuel economy for a car of its size. Good value used. Heated memory seats and driver information center with digital engine parameter readouts (temp, voltage, etc.)
Climate controls are abysmal. No control for temps below 65 degrees. Not possible to be comfortable if wearing a jacket or coat on a cool day. Separate seat cushion from seatback has poor ergonomics, roofline is low for tall drivers, rain sensing wipers are annoying.
