4. 2013 Ford F-150 Regular Cab
Selling price: $23,229
Why mark down a vehicle that's not only been the best-selling in the U.S. for three decades, but whose sales are already up 22% this year -- forcing Ford to add a third shift at its Kansas City plant? Well, when you have a truck that makes up roughly a quarter of all vehicles a company sells, it pays to get the new ones in as quickly as possible. There's also the small matter of this particular generation's days being numbered. A big update and increased fuel economy are coming in 2015, which makes the current model seem like a bit of a gas guzzler. Ford may just be throwing the F-150's rabid fans some gas money before they realize they might just save in the long run by waiting a year or so.
