A Citroen Traction Avant, built in the 1950s, sits parked on a London street, December 12, 2007. Once popular with gangsters in post-war France, the vehicle first produced in 1934 introduced front-wheel drive, a major innovation in modern automobile design, and is recognised as one of the all-time classic cars.
