A coworker got his WRX stolen today at a job site in Jersey City. It happened in broad daylight and in the middle of a public lot. 
I'm now looking into tracker/immobilizer options for my Mazda3. My insurance company says Lojack and Forcetracker are popular options in the NYC area but they don't formally recommend any one brand. I'm also thinking about a manual method. Maybe installing a hidden switch in the cabin that cuts power to the fuel pump or something.
I'm not interested in any pager/viper crap... just a functional suppliment to the factory installed engine immobilizer system (which no doubt has already been hacked).
Do any of you have any thoughts on the matter?
