This is how Toyota works. Refresh, then engine changes. I think the point was this truck is no better or worse than current offerings from other manufacturers. They all claim big numbers but it seems real world is not living up to these facts.
Toyota will come out with the new power plants and drivetrain end of 2015. Look at the 1986 Hilux, the 95 Tacoma, they carried over power plants, then dropped new ones.
I thought every 4Runner that came out was ugly but even the new one is finally growing on me.
Look at it this way, your resale value did not take a large hit. I like the new truck but god damn that front grill is hard to get used to. Personally however, I wish they didn't go mainstream. Oh well. I have four years of payments on my 2012. I'll know at the end of that what to do I bet!
