I emailed service again to see if the upgrade price has reduced due to the reduced price of the SR+. Previously it was quoted at $4500 + Tax; if it goes down to $3000... I'm all in!. Since I seriously doubt they're going to drop the price of the 35k SR... the current difference in price is $2990. I originally paid $35.4k rather than $35k due to a slight price bump in mid 2019 so $2590? Free money for Tesla or wishful thinking? Has anyone else contacted service to see the current price for the SR to SR+ upgrade cost?
