Coincidence. My 530xi is in the shop getting a Passive Restraint warning and a couple of paint chips fixed. I'm in a loaner 550i. I should get my wagon back by the end of the week.

The start/stop button bothers me also. I hate driving with my keys in my pocket. I don't carry alot of keys, but I do have a few lights and fold-up tools are attached to my chain, making it very bulky. So I end up inserting the comfort access transmitter in the steering column slot anyways, I don't know what else to do with my keys. I certainly don't want my keys punching a hole in my suit pants. Therefore I don't get much out of the system.
