i have a 1998 m3 and want the alarm that i think the new 7 series beamers have. I just like the sound of it. I heard somone hit there button to lock and unlock the car and it sounded like a silencer off a gun(that crisp dart sound). is this how the 7 series alarms sound like or is it a aftermarket alarm. Anyways, please let me know. I am looking to find one that sounds exactly like the silencer off a gun. thanks
