What are your thoughts & experience on ZDH, specifically on X5? (Dynamic Handling Package) It comes with 2VM Dynamic Damper Control + rear axle air suspension 2VP Dynamic Performance Control + Active Roll Stabilization 7SZ Dynamic Handling Package For someone who doesn't drive very long distances, but drives every day to and from work with short weekend trips, but almost all city driving, is it worth getting this? I read a lot about body roll on new BMW compared to old one. I must add that I never found old BMW X5 (2012) to have excessive body roll on my daily commute, is it really that much worse on 2014/2015 models? PS: I am in USA.
