It rolls a bit through turns and across lanes during lane changes but it's suspension is a little looser which is great for bad roads. It has tons of head and leg room for big and tall people and the seats are very comfortable. Amenities are on-par for the class. It's much more stylish compared to Buicks of the past and you can tell their trying to capture the attention of younger generations, not just the 55+ crowd (no offense). I do mostly highway driving and combined mileage is about 24 mpg - not great but not terrible for a V6.
Acceleration is good.
