After three months and 5000 miles our white diamond 2010 LaCrosse CSX has been flawless. We average 24 - 25 mpg in mixed winter driving. Optioned with the sunroof & nav system with rear view camera. The 3.6L engine has plenty of pep while very smooth and quiet. In this cold winter weather we love the remote start, heated seats & steering wheel. The interior is luxurious and the seats are very comfortable. Rear visibility is poor, but not a problem with the camera and ultrasonic parking assist. The front roof pillars are somewhat wide and placed more forward and do sometimes obstruct my view when turning. Bottom line - there is alot to like about this car. I would definitely buy it again.
