Why it matters

RM Sotheby's calls the Touring Superleggera spider on the 8C 2900B the Italian equivalent of the Bugatti Atlantic and the ultimate Italian sports car of its generation, counting only about 12 Touring Spiders as extant, seven on the long chassis. Gooding later cited just five genuine long-chassis Touring Spiders. These statements cover the Touring spider type in general, not specifically the 1938 works Mille Miglia cars.
