Do you worry about your car when you take it out?

The more I get into my 64 Val, the more I realize how simple a car it really is. It would be sooo easy to hot wire it. No steering wheel lock or transmission lock like every car built since the 70's. And it's a convertible. I'm thinking when I have it out, the top will probably be down but it definitely will have some kind of kill switch. I just noticed the steering wheel has some somewhat large cracks where the spokes join the hub. If I need to replace it I might consider an aftermarket removable wheel. It just seems to me that it could be started and driven away within about 30 seconds without doing something. I'm not worried if the area has people around but a more remote location might scare me off. It is not on the road yet but I intend to drive it quite a bit but we'll see how I adjust depending on the feeling I get.

I drive my 68 cuda about 1200-1500 miles per year. We have a short season here and its mostly to shows or car cruises. Lots of cruises. It is far from a show car but it means a lot to me. Most people wouldn't even notice a key job on this car. I hardly ever lock the doors and one positive thing is there definitely aren't many cudas on the road so it stands out and would be easy to spot if stolen. But, most people would think nothing of a flat bed tow truck stopping it front of an old car and, winching it on the bed and driving off. Happens all the time and nothing much can be done to stop that unless you happen to come onto the scene and are packing.
I think a judge would understand why you shot the perp's nuts off when he hears it was a Mopar. :)
