Welcome to the forum, John, and congrats on the new2you '08 Limited I had looked at Freestyle's/Taurus X's also prior to the Edge, just liked the overall "architecture". Do post a few pics of the Edge (and prev ride(s))!
How many miles do you have on the Edge? Unless you know the history intimately, I would seriously advise you at least check the condition of: 1) The PTU fluid, and 2) The Battery, aside from the specified maintenance in the owner's manual, found online here:
