I have had this car about 2 weeks. I absolutely love it. The ride is firm but cushioned. Handles very well. On long highway drives getting about 30 MPG, overall in 20s. A luxurious ride and interior. I am over 6' 1" with wide shoulders, long legs so the spacing is important for me. Sitting on the cross Bronx for 2 hours due to an accident was made much more enjoyable by this car.
Mark Levinson upgraded stereo rocks. Panaromic roof, navigation system w/handsfree bluetooth phone connectivity works excellent. Obsidian black w/black interior looks great, perforated front seating for AC and heat. Very roomy trunk. Parking assist with back-up camera.
Only improvement is for the front interior HID lights to produce more interior lighting or add other interior lights for more lighting. They look great but don't produce much light if you are looking on the floor for something.
