North American muscle car expert Jim Bodanis takes us on a tour of his 1970 Chevelle SS LS 6 convertible. And one of the most sensational classics of the 1930’s is the Avions Voisin C-20, known as the Mylord Demi-Berlin. This one-of-a-kind automobile owes its unique design to the engineering genius of French aircraft designer, Gabriel Voisin.
