I just wanted to post a warning to all of you who may be considering the dealer installed ski bag for your car. I brought my car into the dealer to have the bag installed - quoted $400 for the bag ($250) plus labor for approx 2 hours. I later got a call from the service manager, he told me that a special rear armrest would need to be ordered to fit the ski bag assembly, the cost for that part was $700.00. It would cost over $1100.00 to have a ski bag installed in the car!
BMW should really consider updating it's catalog to mention these little things !
In case your wondering, I decided to pass on the bag install...
