Like some others, I'm on the fence about spending $10k extra for the performance Model 3 ("P3D"). I definitely want AWD, and would pay for the 1 sec faster acceleration if there was a tangible hardware difference, but it does at this point seem like it's purely a software unlock and there's no way of knowing whether that will come to the regular AWD ("3D") at a later point. Indeed current tests show the 3D as doing 4.1-4.2 secs 0-60, so Tesla appears to have been generous with their first firmware version (which of course could change a with the RWD version which they throttled from 4.7 secs to 5.1 secs). I have two more considerations about this: one is that I'd probably save $1-1.5k during the first 50k miles through free supercharging with the P3D, the other is that I anticipate selling the car after ~3 years/50k miles, and hope to recover some of the premium I paid for the performance, let's say $4k of it (assuming the total value of Teslas depreciates by 60% over 3 years). So maybe all in all the extra cost or the performance is closer to 1-2k per year for me, which seems more worthwhile even for a relatively small acceleration gain. Does this logic make sense? Any other factors I should consider? Thank you very much for your time!
