Never lock a convertible, if someone sees something and wants in, its as easy as cutting the top. I drive my car everywhere, except the ghetto (did once lol), and I park it with the wheels fully turned and make sure the wheel locks after shutting it off. At least it won't be as easy as rolling it straight out of a parking space, would require what little time it takes to break the steering lock.

I knew someone who had a line lock with a separate battery on their car. Would set the brakes fully when leaving it somewhere so it would be much harder to tow it out of a spot. Not sure how good that was on the brake lines though. I think he would change the flex lines every other year.
