Thanks, capnkirk. It's encouraging that you're getting anywhere from 16-20 mpg (city) with the AWD & Vista options. I drive 100% city and would have thought that the mileage would sink noticeably thanks to that combo. Another plus is that I have no use for an AWD, so that should bump my potential mileage up a notch.
Thanks to everyone for posting your stats and various Edge-buying experiences. I lurk here and at 'Blue Oval News' quite often and it's been very helpful in trying to decide whether to take a chance (and plunk down that kind of cash) on the Edge.
