Hello! I just bought a 2009 Edge the day before yesterday and I must say, I love it! As for the 2010 Edge, I believe the only changes are the way they package them. There's nothing new from the 2009 model from what the dealers here have told me. So for the same car in a 2009 model you can take advantage of the $3000. rebate or special financing.
Mine is very nicely equipped with the 6 disc changer, Sync, Panoramic roof, leather, cargo pkg, dual temp, and 18 inch chrome wheels. It's the SEL FWD model.
Oh, and I got it for under invoice.
Hope this helps. Good luck!
