 I have had this vehicle a couple of months now and have really enjoyed owning it.  I previously had a Ford Freestlye and it seems the 3rd row leg room was a bit more than my new Flex.  This is not an issue for the 6 passenger Ford Flex due to the 2nd row seats slide forward.  The 7 seat configuration does not allow the 2nd row to move forward.  Transmission shifted roughly in low gears.  Buying a K&N Airfilter fixed that problem and now have smooth shifting with no problem.  I think Ford should include a K&N Airfilter from the start to avoid the rough shifting transmission I experienced with my new Flex.  I live in Alaska and the AWD system has been flawless in the snow and ice!
