May I suggest that PW keep the vintage show cars behind lines. The issue I and alot of other vintage car owners faced was constantly telling people not to touch the cars. They would just pull on door handles, run a finger over the paint and what not. Thats not a good sight for the owners who work day and night to keep these old cars looking new and when someone stands next to the car with their belts/watches dragging across the paint, that's a mood killer right there and then.
