As someone still grappling with this decision, the current value of the trade off seems pretty apparent--0.8 sec of 0-60 time + 30 miles of range for an extra 10K. Obviously, whether this is 'worth it' would depend on your driving habits, wants, priorities and needs. I wonder though about resale value--as battery size increases, the low end range models seem likely to become progressively less desirable. I suspect there is very little market for a 60 now that the 70 has come out, for example. Also, it seems that the future 'upgrade path' is more open for 85 owners than 70 owners, at least based on current info. Given that, it begs the question as to whether the 85D is going to generally hold its value better than the 70D? If it costs 10k more new but also is worth 10K more in trade in, then the 'cost' of the higher end model is not so clear. Usually low end models hold their value better then higher end models for most cars, but not sure that is true for EVs. This might tilt the value calculation for some people (including me). What do people think?
