There's a lot of unknowns about towing right now.
Interestingly at the press event for the X1 launch BMW demonstrated the
F48's ability to tow up to 2000 kg (4400 lb).
Not sure what effect a tow hitch will have, if any, on the Comfort Access toe kick sensor. I'm willing to sacrifice that bit of convenience if I can tow a 15 foot trailer or mount a rear bike rack on my X1.
Not sure if X1's come from the factory with pre-wired electrical connections or if that's something that would need to be wired in later.
Also, I'm not sure if having an M Sport will make a difference to the eventual tow package installation, since the bumper is different from the standard model.
