There are a couple of ways to look at this. First, you can invest the money
in an alarm system...your insurance company MIGHT give you a small reduction
in a part of your rates. But as has been mentioned here already....how many of
us now ignore car alarms when we hear them going off? Personally, I would
spend the money elsewhere.
I use a very simple (and free) theft deterent. I remove the rotor and take
it with me. You could also install a fuel shut-off or a battery kill switch. Or
remove the coil wire.
See you in Gatlinburg!
