1st post && a newbie..so please take it easy on me. ;-) I am looking to buy a CPO Tesla with the "2.0" version of the Autopilot hardware being the most important factor for me. When I look at TeslaInventory.com I see these options: (as of Jan 23) Autopilot 2.0 with Enhanced Autopilot (5) Autopilot Hardware 1 Convenience Features (227) Enhanced Autopilot (13) Enhanced Autopilot, Full Self-Driving Capability(95) No Autopilot Package (4) Tech package - No Autopilot (401) Questions: 1) How can I confirm if a Model S has the "2.0 Autopilot Hardware"? (via VIN or build date or ???). 2) If a CPO MS has the AP 2.0 h/w in place, but the original owner didn't buy the "Enhanced Autopilot" and "Full self-driving capability" then please confirm that I can buy those from Telsa once I buy the CPO. From what I have read those options are able to be "activated" by Telsa as they are s/w only. 3) I was surprised to read that AP 2.0 h/w cars with Enhanced AP and Full Self-driving capabilities don't currently have all the features of the AP 1.0 cars. Can someone confirm I have read that correctly, and comment on how long "feature parity" usually takes when a new "major" (6.x, 7.x, 8.x, etc) comes out. 4) By looking at the list above. Which option includes all 3 of what I want: 2.0 h/w, Enhanced AP, Fully self-driving? I think the answer is the top one, but it doesn't list Fully self-driving, so how can I be sure? Are there any other "gotchas" I should be watching out for with a CPO car when it comes to AutoPilot/Full self-driving? (e.g. for sure don't get a Tesla that has been in any sort of wreck as the camera/lasers/whatever will never be the same). Thx for your time and energy in answering these. This forum is REALLY helpful to newbies!
