Great! Thank you.
Appears the sales rep is wrong and heated seats are available . I like the AP but I just wouldn't use it much to justify the cost.
The only question that remains which I don’t think anyone can answer is ... if Tesla decides to “tweak” the software to eek out a few more miles and/or speed, will the SR (base) be included. And, what future offerings will they provide in the future for upgrades?
