Touch Wood! I haven't had a parking lot "ding" in any vehicle I've owned in the past 20 years. I consider it exercise when I park at the far end of a parking lot, uphill of shopping carts, and have to walk a little bit extra to the store I'm visiting.
Today at Wal-Mart I came across an old Mustant straddled across at least 4 parking spots and would probably have "keyed" him in my younger days. To me..anyone that takes up mutiple parking spots is just looking to get their vehicle vandalized.
