John, I don't know about taking out key marks, but you may want to be careful because I feel people *do* single out classic and exotic cars to vandalize. This topic has been brought up on the list in the past: I personally have had food thrown at my DeLorean, but others here have had much more harrowing experiences than that. You may just want to be doubly careful leaving your car unattended for any long stretches of time if you live in a city you feel has problems with car vandalism, but in my view everyone is the same everywhere, so you may not need to worry about this any more than all of us do. (Well, at least *I* do.) Richard
