QUIRKY car designer Mark Ray is flying high on America's roads - driving a converted light aeroplane. Mark was the brains behind the Plane Car, a fusion of a 2003 Cirrus SR22 and a Chevrolet Tracker - costing $10,000. Mark, of Atlanta, Georgia, who owns a paper shredding company, was already turning heads in a homemade Boat Car, which made headlines earlier this year. But his daughter Brianna, 17, thought he was getting bored with it and encouraged him to start a new project. It took five months to build with Steve West of Flex-Fab, Mike Rivera of Rivera's Upholstery and Brandon Geddings of Controlled Motors.
