Pit Viper alarm system.
One pit viper from pet store (check local price)
Dead mouse and rubber mat (check local shops)
When exiting car place mat on seat place large dead mouse on seat for viper to take awhile to eat, place viper. When someone tries to steal the car the open the door swiftly seat down and seat to go to work on the cables and.....chomp they get bite by a pitviper, which I believe is venomious. Caution should only be handled by train animal and snake keepers/trappers.
