Just want to confirm that if you do not have the roof rail option you cannot add any crossbar later on, right? Because on many European car you can add crossbar without requiring roof rails, even the Panamera let you do that. The optional roof rails on the Cayenne are just too expensive. I think every other SUV on the market will let you add crossbar later on.

 

I love the look of the roof rails! They're expensive but not too expensive!!!
