UPDATE:
I brought the smart into Smart San Francisco, it will be Friday before I can get my car.
So the passenger side window glass does have to be ordered, but the wait is only couple of days (hopefully).
Btw, I'm not a big fan of "aftermarket" alarms, as the factory wire harness would need to be tabbed into for the alarm to work. Always causes trouble after a couple of years.
Factory alarms are much better I think, as it is already wired in and less prone to problems.
Do you guys agree with this reasoning?
