15k: Factory Sleeper: 2010 Ford Flex Limited EcoBoost

Just how do you describe a Ford Flex with EcoBoost?  You could call it a Texas sized Scion xB, a station wagon on steroids, a meat head's minivan, or a small airport shuttle...but I'd simply describe it as fast.  Faster than it should be and fast enough to whoop on some cars that can't seat 6 adults comfortably.  The 0-60 mph spec of 5.8 seconds isn't shabby, but where the Flex EcoBoost comes alive is the 30-50mph freeway merging lunge that only takes 2.8 seconds.  This means your Flex is faster than a 2014 GT Mustang 5.0 or Camaro SS and on par with a 2013 Porsche Boxster S.  Find this 2010 Ford Flex Limited EcoBoost here on eBay currently bidding for $16,500 reserve-not-met with 5 days to go, located in Roan Mountain, TN.
