Future Prius owner here, and I'm going back and forth between the 4 and 5. I like the idea of a sunroof for the extra light in the cabin, but it's not an option with the 5. Any idea why? And then I'm used to the higher end headlamp systems in other cars so I like the idea of the headlamps in the 5, the auto leveling, the fog lights. Also, on the toyota website, it lists two option packages with the 5. I don't want lane keep assist and auto parking, so i'd rather have the NY package. But then when i build one on my ipad i dont even get that option and my dealer shows all current and future inventory with the more expensive package, no NY. So it's going to cost me extra dough for features I dont want. Does the third gen prius 5 exist anywhere else with the NY package? Thoughts on 4 vs 5? Thanks!
