Hey guys, im about to pick up my X3 in a few days, and i get a call from the dealership saying that I havent installed an alarm system on it yet.  The price they were asking was $600+ for the system and installation.  Call me crazy but isnt that a bit much for the alarm system?  should i go to another dealer to find a better price?  and if i do install an alarm system not thru the dealership i leased the car from, will that nullify my lease?? 
thanks in advance guys...
