I've owned a few Vee Dubs. I wish this was my photo, but it's not...although my '72 Karmann Ghia was exactly like this one:
A weird one I owned was a 412 like this:
As you may know, since the engines in all early VW's were air-cooled there was no heat until the engine got pretty hot and even then marginal. So in the 412 they had the brilliant idea of using gasoline from the tank, igniting it in a flame which heated an airbox and allowed warm air to flow into the cabin even before you started the car!
