Hi,
If I can chime in with my experiences with my Flex experiences ; - ) I will say the auto park feature is almost freaky. We have a 2010 Ecoboost Flex with all of the trimmings and the auto-park feature is one of things that you just know will screw up at some point - it hasn't yet so far after many, many uses.
I thought it was a gimmick at first but not now.
