I park 2 cars on the street i a major city.  This gives me the piece of mind to know that if a car gets stolen, it will most likely be someones else's ;)  Goes on and off easily with the key and secures well to my steering wheel.  Only downside to using the club is that you have to remind yourself of the screwed up community you live in where you have to put on extra security measures to make sure someone doesn't steal your car.
