Just bought the car end of Dec. I got the Luxury package Mark Levinson stereo and nav 4000+. There are too many high tech feature to learn. It is very hard to find a Luxury Package, it took me about 4 months to find one. Acceleration and braking are excellent.
Personalized setting, AFS Xeons swivel as I turn, 4 Pistons caliber brake, heated seats, automatically turn on wipers when rain drop on windshield
