WOW Stolen Cuda found
Put a tracking device on your car.
They sell them for cheap and can send signals to a smart phone, GPS as well as trigger things like ignition kills outside of parameters that can be set.
This would have prevented all of this. The systems have their own batteries that recharge from the 12v system, so even if someone disconnects the battery and tows it, unless they can find it and tear it out of the car (because they are somehow aware of it) within the time it takes you to locate or before the system warns you that the car is in motion, without running, they will never manage.
You don't need to bury it in some extremely difficult place. Just put it somewhere in the car that is out of sight and takes a reasonable amount of effort to dismantle.
Most of them send a text message to your phone if they go dead or if the car is moved without the ignition being in the run position.
