Buttercup

"Buttercup" is a mythical 1957 DS (9/570660) owned, driven and cherished by Bob Dircks in Australia.
She came in Paris for the 50th birthday of the DS, it has driven about 800 000 km, and still uses its original crankshaft, crankcase and cylinder head.

More pictures of her can be found here:
