Our solution ...
When we installed the new Painless wiring harness in our Special last year, we also spliced in a "kill switch" with a hidden key. When we park it somewhere I just turn the hidden key to the "off" position, pocket the key along with the regular keys and off we go. There is a generic black plastic cap that is a push fit over the key unit so that it "camos" right in with the rest of the car and doesn't stand out or look out of place even if they looked right at it. If anyone actually tried to hotwire our car it just wouldn't start or run .... and they probably wouldn't take the time to try to figure it out ...
