How about LoJack? I heard it was about $500 to install, you get an insurance discount, and its pretty reliable...? Not too sure though...if I gonna park my car for a long time (month or more) I take the shifter out
Takes about 10 minutes, and if they tried to break in the car, they'd get a pretty nasty surprise upon entry!
On a lighter note, I've noticed that the ghetto punks around here don't even pay my car any mind because its unricey and no wing...I guess that means its not a hot item! I guess that's one GOOD thing about the import craze
