That's true, you do have to report your car stolen to LoJack in order for them to put the word out.
If your wife's opposed to you having a sports car, then get a 91-92 Galant VR-4. 4 doors, doesn't look fast, cheap insurance, factory turbocharged AWD with 4WS with leather and a 5-speed. Sleeper. She'll love you for getting it, just don't tell her that it runs 14's bone stock. They can be had for $1500-$4000. I'd lean toward the $4000 side of them if I were you. They are getting up there in years, and you want it to be as complete as possible. I know a few guys in the 11's and 12's with them, and they still appear bone stock with the hood closed.
