I picked up the 2007 Edge SL+ from the dealer on October 1. Since then I have put 17000 miles on it (I am in the medical sales business covering 3 states). I changed the oil at 800 miles (don't trust the factory oil) and every 5000 miles (not 7500 like the manual suggests). Always Mobil 1 5W-20 and a Mobil 1 filter.
I had an 01 Lincoln LS that I put 130,000 miles on with the normal wear-outs and repairs. Considered the MKX, but the price differential was just too great (I purchase FMC products under my fathers retired Ford purchase plan).
So Far So Good. I had to have the roof buffed by the dealer due to a crummy carwash, but that is it.
FAST, ECONOMICAL, and QUIET. . . .Love this Car.
