Oct 2016 and newer will have the capability for FSD according to Tesla. It is a $3k upgrade from EAP, and EAP means it has AP 2 hardware at a minimum. Note that MCU versions were updated sometime in late 2017 I think. To get all the features coming out in version 10 today, the car needs both AP2+ and MCU 2. Otherwise you don’t get Netflix and some of the games, etc.
So it depends on what you are wanting.
