Mannyrock, actually there have been several occasions when I purchased a rare and valuable car for much, much less than one would expect because it was filthy and I knew I could clean it up with no problems. The Bing car below was one of those items - I wish I had taken a picture of the car before I cleaned it - the roof was a dirty gray/brown, and the sides were just plain dirty.
If you look closely at the doors you can see what looks like damage to the litho wood side treatment - it's not - it is some kind of partial litho print failure - the doors on the other side have the same pattern.
