I know this question has been asked above but I'm reposting to keep the question as relevant as possible.

Does anyone know if the 2011 X6M allows for a tow-hitch. My dealer told me it was NOT possible and I saw one post above that made the argument that it's not possible but I'm looking for some evidence so I can put the issue to bed or dig deeper.
While I don't really want to tow anything, I do want to add a tow hitch-mounted (mountain) bike rack. I know there are plenty of bike racks that don't require a tow hitch but the only i like, slides into the hitch and conveniently pivots down so one can open the tailgate. (it also acts as a fantastic bumper for rear-enders).
BMW offers a bike rack that plugs into special holes in the back of the car but it's kinda a PIA to take on and off.
I'm also open to suggestions on convenient bike racks if anyone has any idea?
Thanks for any suggestions.
