They tack that on to make you think you are getting a better deal than you really are. I just looked at a 2010 GT, $35,500 sticker. With Xplan it is about $33,400 or so and take $2,500 off for rebates. I have another special offer from Ford for another $750 which I did not tell them about. My dealer would go no lower, only said they thought the rebate should be higher. I told them we were about $4,000 off especially when they offered me $18,000 for my fully loaded 2007 GT with 22,000 miles. Unless the deals on the 2010s get better, I am waiting at least a year and picking up a 2011 GT.
