Don't rule out the possibility of buying '15 or '16 carryover. There are some really good deals out there.
I like some things about the new auto. mode, but not sure I care for auto downshifting when in manual mode, at least in some situations.
Also I don't really like the drivers seat belt speed limiting function of the '17 ( yes, I realize it can be bypassed, just hate the gov't cramming safety features down our throat).
I noticed in cool or cold weather, unless the '17 is warmed up it likes to stall after you take off in low and it tries shifting to 2nd in auto mode.
