I would imagine you can get the used one much cheaper than the advertised price. Units depreciate heavily once driven off the lot and it's pretty dramatic for the first few years until it starts to level off. In the case where it's a year old you can make huge savings. That said 28k miles is a LOT of miles for one year of use. Was it a rental? That's 500 miles a week! It's out of warranty and it's almost out of the factory Ford warranty of 3/36. If the mileage were half that (what I would consider the high side of normal) this would be a no brainer but that's a lot of miles for one year. Not that the Chassis and drive train can't offer another 100k trouble free miles, but it's an indication that it was used heavily in a very short time.
