I have not seen or heard of any SR AWD 7. Unless something change recently, all LR7 have been from Fremont only. SRAWD is not even available to order via online configuration. It's like a "secret" model.
Yes. My SR 3 was similar off menu in 2019. But now the AZ rep denies SR AWD Ys existence, so "super" secret or impossible for 7. Also it was a $5k price difference for the RWD 3, vs only $2k for SRAWD Y
