Volkswagon Graveyard

Found this unusual sight while driving in rural Oklahoma towards Oklahoma City. The faded and rusty sign for the garage suggests this was once a thriving auto repair shop, probably specializing in Volkwagons, but now there are about a hundred or so just sitting there. I keep wondering why somebody hasn't made a business from picking up all the rusting old cars in the midwest and melting them for scrap. There's lots of them out here.
