European barn find hunters told stories about the mythical collection in France for decades. With over 100 cars, and various makes and models, it included some of the most desirable pre-war models and sports cars. However, nobody had any legit pictures or information. Then in 2015, the news shocked the car world that the collection was uncovered and that all of 100 cars, 60 of which could be saved and restored, were up for sale (via Auto Week).
The most exciting part of the Baillon Collection was the fantastic Ferrari 250 California Spider, once owned by famous French actor Alain Delon. He used the car in Europe and America. Produced in just 55 examples, it featured a race car drivetrain in a seductive roadster body. Even though this example was sold as a restoration project, it managed to fetch over $18 million in an ArtCurial auction.
