Between those two cars, for me there's no contest -- the '18. To each his own, of course, but I specifically do not want the Dynamic package -- I seriously dislike those additional "driver-assist" things (my car has the Static package). I almost never use cruise control, so the adaptive feature doesn't matter to me, and I truly hate lane-keeping "features" that beep at you (or worse, make the steering wheel vibrate or, still worse, actually take over steering the car) if you get near or touch a line. I'm often near a line because I want to see ahead -- beyond the SUV in front of me rather than just the back of it. My '18 Ti Sport has the Performance Package and, while I don't think it's necessarily a must-have (the car is still great without it), I think it's superb and well worth the money. Also, especially given the huge mileage difference between those two cars, you could look at the 700 miles distance as a wonderful excuse for a road trip...
