Yup, I have a friend that had a very expensive Lambo. When he would leave it at the shop he would ask where they wanted it parked. Then he would take the keys and registration with him and tell them "if you need to move it or start it, call me".
That was after he left a previous car at some shop for work (window tint) and what do you know? It disappeared from his driveway 2 days later. Keys and remote had been copied and they had his address from the registration.
