I am considering a pre-owned model 3 from Jan 2018 as compared to a new one. Compared to a new LR AWD, I would save around $7,500 on a 2018 pre-owned, 22k miles, black on black, premium interior and FSD. The end of the vin/serial is 03888. I drive only around 6,000 miles per year so not too concerned about hitting my mileage warranty cap, but would obviously run out of factory warranty two years sooner. I don't live in a cold climate so I am fine with RWD over AWD, and the slightly lower acceleration. I was researching for major changes and it seems like the seat designs were changed (more leg support for rear seats now), and some cosmetic changes to the front seats. I also noticed there are some changes to the UV protection on the glass (older has more UV protection on the back window rather than just the top). My understanding is FSD will make me eligible for HW3.0 upgrade down the road when needed. Is there anything else i would lose in terms of current or future autopilot upgrades? Any changes to the sound system? Is there ANYTHING else that I am missing or should consider when going for this 2018 vehicle?
