While I am extremely happy driving my 2016 model S P90DL I am looking for a good or prudent excuse to support Tesla and get the latest and greatest. Upgrading a two or three-year-old car does not come cheap so for me it must be compelling. Currently the 10 kW bump in battery does not quite provide enough motivation to get me off the fence. A combination of some or all of the following would probably do it though...Soft and automatic door mechanisms as in the X, a BMW like comfort seat, HUD, slightly more interior color choices, coat hooks, upgraded sound insulation, proper blind spot detection and a more elegant and functional armrest area with better smart phone integration. Even something as trivial as being able to see both battery percentage and distance remaining at the same time could be persuasive. What would it take to upgrade yours?
