1949 Delahaye. This 2-seat roadster was owned by English movie star Diana Dors. It made a welcome debut restoration at the 2006 Pebble Beach Concours where it graced the shoreline beside the best examples of the marque. Later, the original engine was sourced and it was offered at Sports & Classics of Monterey by RM Auctions with an estimate of $4,000,000-$6,000,000 USD, but sold for $3,300,000.
