I am ordering a 2013 X5 5.0. In addition to using this X5 5.0 every day, I am an enthusiastic driver and will attend BMW CCA events. My dilema is should I order BMW Sports Suspension, which allows me to get the upgraded V-8 engine, or order the adaptive suspension system, or both or no supsension package? My goal is to have a comfortable daily ride and still eliminate much of the roll/swaying that occurs with a 5,000+ pound SUV. I look forward to hearing your thoughts and comments. Thank you.
