I planned on buying new in 2015.I did plenty of research, talked to F150 owners and got feedback from salesman. I found most leasers do not care about the engine. 65% of F150's sold have the 3.5ltt. 700,000 on the road. It is $2,395 more than 5.0l. Salesman say customers have a concern/distrust of Eco-boost. It is #1 issue with trucks. Ford's use of rebates, is what has helped sales on the EB. Expedition are not selling well. The dealer had no flyers to give out and only one Platinum model on lot $75K(wow!). Owners with problems, have had big problems. Bad motors, turbos, Timing chain issue, carbon/sputtering issue, white smoke and rough idle. Many that like/love it, are not seeing fuel savings and complain. Sales of extended warranty have gone up, for Ford trucks and resale down.
