[The Deuce]

Along the lines of Chirs's idea, pull the wire from the coil to the Distributor. A little cleaner than grabbing the distributor, and a theif would not likely go grabbing other wires to make this work. After all, there are ways around this, but the car won't run real well.

If somebody gets into your car, and can't make it start chances are they will leave it. Had a friend with just an LED that he would switch on when he left the car. Looked just like my alarm when they were on.

I've thought about getting the boot. Like parking people put on your car. No one would mess with that.
