We have had the Model X for almost 2 months and I have fallen in love. It is actually my wife's car and I find that I do not want to drive my 3 year old Model S, never thought that would happen. So now I'm struggling with weather to keep it or buy a new Model S with all the stuff the Model X has. My thinking is to wait til next year and see what battery is offered and then make the switch. Thus the cost me more title.
