If the car is totalled, your insurance company will pay off the value of the car to BMW, effectively ending your lease agreement, so you'd get your SD's back.
Nearly every leasing agreement has the requirement for a SD, FYI.
All the quotes I've got so far have not included a security deposit, I'm assuming the first month's payment is considered that.
If what has been said in this thread is true, then its a no brainer to put a security deposit. From my calculations I'll save about 30 bucks a month if I put 7 MSDs down
