I have been shopping for a model X and had a question. I have crunched the numbers and can get a CPO 2016 Model X with all the goodies that I want or get an Inventory model X with very few options (actually it will be a bit over my budget). My question is would you guys / girls spend that amount of money on a car with the older "maxed out" processing power of the first version autopilot? I love the CPO car but my second reason for buying a Tesla is the autopilot. On the other hand I am thinking full self driving is probably 5 or more years away (which I will still be paying on either)!!! I'm stuck.
