You're right about the Edge getting scarce - at least the AWD is. I have spent hours on the phone tracking one down with the specs I'd like to have. Have basically burned through Georgia, South Carolina, North Carolina, and now have a dealer checking Tennessee and Ohio. Maybe I should take this as an omen. I'm not having much luck. Seems like each time I find one "it was sold yesterday" or "we traded it to another dealership this morning". Ugh!
The Ford dealership here in Orlando said he is pretty sure the incentives that expire Monday will not be coming back. If the pickings are getting slim then they don't really need incentives. They pretty much sell themselves.
