Whats your budget? 25K list price or 25K out the door?
I'm going to stick with my Highlander recommendation for long term family hauler duty...however
If your heart is set on an Edge, I think you might want to focus on the V6 models vs the turbo4. Turbo 4 is a bit of a dog but the tradeoff is that you can get slight newer 4 banger models for the price of a V6 model. I suspect that the fuel economy improvement over the 3.5 might not be worth dealing with lack of get up and go.
The Turbo 2.7 is another matter. Might be out of your price range for one with decent mileage. You can probably nab a certified 2015-2016 Flex with the 3.5 with under 40K for about 19K-22K. From what I recall, it should be solid. Just make sure it had the throttle body recall done if you get one with a vin impacted by the throttle body issue.

I'd also consider doing your homework on a Kia Sorrento . You can probably grab 2017-1018 with low miles. Avoid the Turbo 4.
