Not to sound like a party pooper ...but you might want to look into the "Viper Alarm" SST model that signals you up to a mile away if some one breaks in aside from setting off an alarm and locking out your ride. Of course no one listens to the alarm but if your close enough you can woop his but or run down to the rig and break his F_ _K ing head!!!!! Then Kill him.
Then beat his ass some more and Kill him Again
