Selling my Viper 500 alarm with 2 remotes and a back up siren (which can only be turned off by key) from my 95 M3. It is already wired into a BMW factory alarm harness so all you have to do is connect it to the ignition and plug into into the pre-wired alarm harness on your car. It includes started kill, door lock, silent arm/disarm, panic, code jumping, etc.
New it was $460 ($370 plus $90 for the back up siren), I'm asking $190 for everything. Please email with any questions.
