Have not. Was looking to take advantage of the big rebates on the 2014. Will give it a look. Little leery buying used without knowing history.
You can search for new vehicles on cars.com. I have found vehicles that way. Search for a new, 2014, f-150, silver, crew cab, 4x4, and that should help narrow it down. Find a truck that look like it has what you want the copy and paste (you will need to delete everything after the = before pasting) the VIN here to look at the window sticker.
