Could I Upgrade a ModelS to AutoPilot built after October 2014 (p50000 and above)?

If you are looking at a CPO that already has the AP hardware then tesla would have turned on AP software and priced it accordingly. So the price they advertise most likely has AP factored in and you don't have to pay extra.

Mine was Oct 2014 built with VIN 57k and had AP enabled.
 
If you have access to the car, look for the camera on the windshield. The opening is trapezoidal. Also, the car will have like a dozen ultrasonic sensors between the front and back, and a radar below the nosecone. Once you know what to look for it's pretty easy to tell which cars have AP hardware.
