Now that unlimited charging is gone (except for orders prior to 1/1/2017), I am scratching my head if anyone choose S90D. With only 3K difference in price, and about 17Kwh more usable battery, it is beyond me why Tesla would even sell S90D option. Still a wonder how 60 to 75 is 7K price upgrade when the juice is only upgraded 10.2Kwh. Tesla Logic is quite interesting... I wonder if any TMC members who have recently bought 90D just to save 3K.
