Q: Self-Leveling & Adaptive Drive

[salehm]

Hi all,

In X6 35i Configurator, you can select Rear Self Leveling but not Adaptive Drive.
In X6 50i, you can select Adaptive Drive but not self leveling.

I thought that there is no need for self leveling if I have Adaptive Drive but I was surprised when I saw X6 M Configurator where both come standard selected already.

My question is: in X6 50i; can I ask BMW to add Self Leveling along with AD? Do I still need it if I have Adaptive Drive?
