I'm getting rid of my 2013 Model S this week and have 2 different options to trade it in for. The first is a 2016 70d with the nose cone, AP1, and 2nd gen interior for $30k or a 2016 75d with the facelift and AP2 (enhanced autopilot) for $37k. What's the better move? Is it worth the extra $7k for the facelift and AP2?
