Hello, just joined last night, I saw your section for edge with the most miles on it so I thought I would join and see what everyone else is saying about their edges!
I have 2 edges, 1 is my wife's 2010 limited white platinum, and my 2007 SEL AWD, with 283,000 miles on it, I have owned it since march of 2009, bought it with 36,000 miles on it, regular maintence, battery, wheel bearing and front hub, speed sensor, just did the brake booster last week, and 3 weeks ago did the front lower control arm. That and brakes and tires that is it! Still have not changed the original spark plugs, or tranny fluid. Earlier this year I had some tranny slipping issues and bought a quart of Lucas tranny fix and ran this for 5,000 miles before all slipping went away.
Just thought I would share my experience with the Edges.
