Purchased the Ultimate Luxury Package - even though packed with features the car remains intuitive to operate and is VERY easy to drive - performance better than anticipated but performance is not a reason to purchase. The quality is excellent - used for commuting. Can't get over the quality. Only one nagging issue - I am 6'2" and am VERY close to the roof panels, even though I purchased the panoramic roof for the extra clearance - drivers over 6'1" beware and make sure that you are comfortable with the head room - vision at stop lights can be limited.
Panoramic roof, park assist, break assist is excellent, integration of Bluetooth with the NAV system is very well done.
More head room and increased visibility out of the front of the car. More control over tuning the stereo - I've gotten used to aftermarket steroes with those features in previous cars.
