Although some are just too far gone.
This video might be a little bit difficult to watch. It features the cars which once belonged to the late Roger Baillon, left for decades to rot away. These cars were only recently discovered, and as you would expect, will be heading for auction. That is, some will be. Only 60 of the 100 cars have actually been deemed salvageable by Artcurial, the French auction house handling the sales, and as you can see in the video, even these are in poor shape.
The most valuable car in the collection is a 1961 Ferrari 250 GT SWB California Spider, but there is also a 1956 Maserati A6G Gran Sport Frua and a Bugatti Type 57 Ventoux of unspecified year, but it would be sometime in the late 30s.
