Tesla discontinued the "original" MY SR in February 2021 (at least in the U.S.), although it was still available "off menu" for a while. It had initially carried a base price of $41,990, then Tesla lowered it to $39,990 and shortly after that it was discontinued.
A new 2023 MY SR is available "off menu" with a base price of $50,990. Unlike the 2021 model which was RWD, this version is dual motor AWD. Since Tesla doesn't post all of its new inventory online, anyone interested in a vehicle like this may want to talk their local sales advisor regarding potential availability. The SR's range estimate is 279 miles compared to 330 miles for the LR.
I remember buying my SR 3 "off menu". Store in AZ denied SR Y's existence on Sun. I guess I got the wrong rep. Not worth the range/$ gain unless they bring back the base price of $41,990 or even $39,990 (any lucky unicorns who actually bought? !)
