Interesting pictoral documenting the restoration. http://www.yokoban.net/018-benz220s.html Apparently there's a backstory to it:
After:
Before:The owner owned this thing since it was brand new, and he was in his 80s. His son wanted to restore his dad's car for him, but just a week before it was fully restored, the dad died. The dad did see the car before his demise - when they took pictures of it in fron of the house, they chatted up the good old times and he brought out a pile of yellowy B&W photos of the car when it was new, and pics of the years they spent together. The Mercedes was not a museum piece, until they hauled it in for restoration, the father used it for every day get around... The Mercedes engine still starts at first try today.
