I bought an Edge in 2015, and was just looking at used Escapes for the wife. I sent an email to the dealer that sold me an Edge and asked if they could provide me with the window stickers on a couple used Escapes and they did it without a problem.
Or if your dealer is selling any used Edges, you could say your interested in their Edge but want to compare it to some others you have seen. I think they would quickly get you the window stickers.
