What is the average range for a used 75D at 90%? Still having trouble to decide between the two cars..
There are ways to figure that out but you also have the benefit of a 8 year unlimited mile battery warranty with any Model S/X built before 2019 I believe. I think the 75D is essentially the same chemistry as the 90D but has 2 fewer modules. So any concern about degradation etc would still apply and I can't imagine the 75D has more range than the 90D even if it is a better chemistry revision.
You won't go wrong with either car. Just think about what features you value and how much it would cost to get the other set (i.e. MCU1 to 2 and other features are possible with more $$$) but nothing can add more modules to your battery.
