This undated photo provided by Ford shows the 2014 Ford F-150 STX SuperCrew truck. Americans are paying record prices for new cars and trucks, and they have only themselves to blame. Many in the business think prices will moderate some because people who kept their cars through the recession and haven't replaced them yet won't load up on options. Ford will try to please them this fall by adding a four-door cab to its F-150 STX line. Previously, the STX only came with a two-door cab.
