Actually, I think If I had a great big living room well that was 40 ft high and painted stark white, that black 911 that I posted, drained of all fluids, would make an awesomely provocative wall-hanging. And way less $$$ than an original Warhol.
I think what continually keeps the price up on 911s, even with their high production runs, is the same thing that old E-types sell for way more than their production volume would dictate....they are just plain SEXY.
