Thanks Sportline. Very much appreciate your compliments on the invisihitch.
I do wish BMW offered a factory tow-prep package in North America on more than just the X3 and X5. They do so elsewhere. Admittedly the towing culture is different in the U.S. (very SUV centric), but still a LOT of U.S. owners want to attach a bike rack or ski rack to the rear of their sedans...
