Since its inception in 2008, the Ford Flex hasn't exactly seen sky-rocketing sales. While the wagon/minivan/crossover blended vehicle is certainly unique, it just didn't take off as expected. There are many possible reasons for this, one being the success of the equally spacious Ford Explorer. But rather than dwell on previous sales, the Blue Oval decided to simply dust off the past and move forward. In order to keep the wheels churning, the automaker will upgrade the Flex for the 2013 model year.
