I'd have to suggest against trading in unless the Gen 2 is just all around something you want more. The good thing is, your Gen 1 has done the biggest part of it's depreciation which you would start all over with if you buy a Gen 2. Secondly, you know how reliable your '15 has been and it's got sufficient range for you. I really have no big complaints about the power of the Gen 1 other than I wish it had a little more to give when passing at freeway speeds but for around town it's got plenty of power. Exterior vision is lacking in the Gen 1, and not sure if that was addressed in the Gen 2, but that, in combination with the extra safety and convenience features is something that would have me contemplating and weighing in the cost difference.
Most models do tend to have some reliability setbacks after a major redesign and it appears the Gen 2 is definitely firmly in that camp. Unfortunately the later 17's and '18's haven't been out long enough to know if they took care of most of these issues but we do know the Gen 1 has really proven itself for long term reliability.
