Tesla manual says leaving car uncharged can result in damage that the owner is responsible for! Go look it up.
I already laid all this out, from the opinion of someone who has owned a model 3 since 2018, and has read almost every thread here in the model 3 subforum (some multiple times) since 2018.
Yes it does say that, but it doesnt say "for a month" or give any time frame. You are also assuming there is the same amount of drain in an undelivered car as one an owner might have, that could have third party apps running, stuff plugged in draining the 12v, etc etc.
There should not be an issue with these cars for at least 3 months, and likely not even then, depending on what the starting battery charge was.
There is a battery warranty of 8 years or 120k miles at 70% retention. That wont change on these cars. If that is not enough for you, then you need to decide what to do. My advice though, would be if you might want to re consider the purchase at all, because batteries ARE going to degrade, and if you are super duper stressed about it before you even get the car, even after the information laid out, that likely wont change after you get the car either and no car is worth a ton of stress.
Anyway, with that, I will wish everyone good luck with their decision, and will exit from this thread.
