I never leave anything of value in view. I also generally don't lock my vehicles. I've only ever had someone go in one of my vehicles once, and it was a neighbor kid who wasn't right mentally. He took the owner's manual from my 240D, but left me a pair of eyeglasses and half a pack of chewing gum. It was about a year before I found out who did it.
