Talbot Lago T26 Grand sport SWB Saoutichik is displayed for auction during the Retromobile show in Paris, Tuesday, February 3, 2015. 60 rusting motors, which include a vintage Ferrari California Spider, a Bugatti and a very rare Maserati, were found gathering dust and hidden under piles of newspapers in garages and outbuildings at a property in France.
