With the year 1957 selected, Vicki Butler-Henderson and Alex Riley argue the case for the best city car released in this year. Alex makes a case for the BMW 600, while Vicki drives one of Italy's best exports in the Fiat 500. The winning car is selected by a judging panel made up of motoring experts featuring journalist and presenter Jason Barlow, motoring author and comedy writer Richard Porter, and RM Sotheby's car expert Will Smith.
