Very happy with the car. Drives really smooth, very quiet, and comfortable. Steering is firm and precise. Some body roll exists, but the car handles well (for it's size). Good throttle response. Controls are intuitive and simple, nicely laid out. Interior layout overall is great. I'm up in Toronto, and had it out on a couple of cold days. Warms up real quick, and defogging works real quick too. Visibility isn't great though. There is a pretty big blind spot to the front left (due to the roof pillar/left mirror). It's actually quite annoying for making left turns, or on windy roads. The car is wonderful otherwise. Don't know fuel economy yet, only had it for a week.
Quiet, smooth drive. Interior layout and quality. Very comfortable (even for tall people).
Better visibility! The new OnStar rear view mirror is too big, not allowing me to attach my nice wide angle mirror. Bigger glovebox would be nice. Ability to turn off certain features would be good too (OnStar, ABS -> stopping dist is worse in deep snow/gravel w/ABS)
