Concept Car of the Week: Ford Forty-Nine (2001)

Over 1.3 million orders were placed for the 1949 Ford before it even went officially on sale. The revolutionary post-war design with slick slab sides and semi-covered wheels became a symbol of American optimism. "The inspiration for the Forty-Nine concept comes from the passion and excitement of the original, combined with the imagination of people across America who customized the car and turned it into what they thought a really great car should be," said J Mays, Ford's vice president of Design at the unveiling of the retro-futurist coupe back in 2001.

These days the 914 holds something of a ‘cool factor', generally considered as the ‘black sheep' in Porsche history.
