Do I get a 2015 F-150, or wait for the 2016? The reason I ask is because I don't want to get one now only to kick myself in the ass because the 2016 offers stuff not available on the 2015. The only real thing I could think that would make me regret the 2015 is if the 2016 3.5L ecoboost has the navigator tune or the new 10 speed trans. What does everyone think?
