John, for what it`s worth, making a statement like your `invitation only' one is the quickest way to get guys to keep their cars in the shed. Yes, you are right if it`s an unknown random guy that wants to drive someone elses car, but what would you now do if say Brett Willis wants to have a drive in Ralph Mossmans car or the biggest fish of all .... if Jim Richards gets to drive his old Mustang. Is that different ....... that`s what you have a drivers briefing for, so everyone is on the same page.
