So gave in and called SA. Was going to accept regardless of chip status. OD 11/15ish, previous hold in Dec after first vin, hold released later that month. EED finally narrowed to two week window late last week with VIN yesterday (162XXX). MSM, Black interior, Aero, no FSD.
I call and awkwardly ask if they have any more information on when car will arrive or when it was built. Told was en route from California and to be expected near the end of the narrowed new 6 day window. Followed up by asking if they knew when it was built and was asked "Are you trying to see if it has the AMD chip?" Said yes, but would take it either way, which is true. They were like let me check and "yes, it has it." They did not say when the car was built though, but I didn't ask again. Hopefully this is accurate. If not, still very excited.
