Actually, I never really "got" one. I just bought the Edge back towards the end of May, and before I bought it, I had my friend run the VIN to see the history. He said it was pretty clean but had an open Recall for coolant corrosion. You may want to research it -
The service writer at dealer said my 07 Edge has a recall on the heater core and asked me if I had any heater issues and I said no. Apparently the core has extended warranty of 5 or 6 years and 105k miles. can't remember if he said 5 or 6 yrs.
