Question for you owners, experts. Looking at getting a CPO model S. One has AP 2.0 and the other AP 2.5. Both have FSD so they can be upgraded but is there any advantage (both have MCU 1 and I won’t upgrade that right away) to getting AP 2.5 when both can do self driving and will be upgraded? I think I read AP 2.5 can do sentry mode even with MCU1? Thanks in advance
