Probably nothing as I was pretty happy with my Edge AWD and this was more of an impulse buy. We were looking at F-150, Tundra and 4Runner but F-150 or Tundra 4x4 w/ leather was a cost I just couldn't justify for a pickup, and the 4Runner is outdated. With that said, other than a few times backup camera failed, I have been very happy with the ST. Fun to drive for an SUV.
