Have 26,000 miles on vehicle. No problems whatsoever. Only work done was routine oil changes - so far very reliable. In 2007, Ford did not offer the sync option for audio/mp3 players (which is now offered on 2008 cars). I would have preferred that over the wire connections that I must make now. Overall experience is that I am very happy with this car and would buy it again. Combined hwy/city mileage is a solid 18mpg - don't expect more from AWD equipped car. Although the Edge has been out a year now, I still get a lot of questions from people about the car. The styling appears to be popular.
Roomy (We have four person family), versatility, styling, safety, power, & vista roof. I also like the tire pressure monitor, it came in handy twice when I was getting flats (nails) and allowed me to get repairs without getting stranded. Headlights are excellent.
I agree with the comments on the angular headrest - they could be more comfortable. Provide more flexibility in ventilation controls. We added small circular mirrors to the outside mirrors to improve side visibility. Add adjustable pedals option & rear stadium seating for shorter people.
