What does lojack cost these days? It used to be really expensive, but it must be more reasonable now...
As for theft, are they trying to tow it, crack the ignition, or do they have a key?
So much for sleeping now, you know they'll be back...
Good luck,

btw, it's fun to pretend that you might shoot the bad guys, but the reality of the situation is that you'd likely have no reason to do so. If you managed to hit one of them, and managed to avoid criminal charges, you'd still be looking at a civil suit that would ensure your criminals would live well for a long time. Actually kill them and you'd pretty much kiss your life as you knew it goodbye.
Theft is what insurance is for, best case would be that it's not recovered. Getting yourself beat down or shot becomes one of the least of your worries when you decide to pull a gun without having shots fired at you first. This is coming from someone who works in a town where every household is required by law to own a gun, and the proper ammo for it... They gotta have 'em, God help them if they use them though....
