I bought QX56 2011 without Hydraulic Body Motion Control and during first 2 months I notice that ride was not that soft that I expect so I went back to the infiniti Diller and I did test drive with Hydraulic Body Motion Control so I end up trading in my first QX to this one I love it is so much better ride and cornering . I also love seats ventilations as well that come with deluxe touring package and 22" weels as well .
