I'm not a Ford Edge owner, but I looked at one pretty hard when I bought my Freestyle. Here would be a suggestion if you aren't looking at new cars; check out a Taurus X.
I wanted to like the Edge. I loved the drive train. What I didn't like was that it really didn't have any more usable space then my Volvo wagon. A CRV, which is quite a bit smaller, had way more cargo space.
I realize cargo space isn't the determining factor for car purchases for most folks (it was a real biggie for me). However, I also liked the way the D3 platform rode versus the C3 platform. It just seemed more stable and better-handling to me. Both cars share the same drive train.
One big difference is styling. The Taurus X kinda looks like a toaster. The Edge is much cooler, particularly on the inside.
From what I've seen, you can get a much better deal on a Taurus X, given its lack of popularity, so that's another consideration.
