Been a lurker here for a few month now but wanted to provide another data point :
Order complete on Feb 1 - RN114450950 Plaid Midnight silver metallic, 21", Black/White, CF, Full self drive
Didn't get a date shown until may, showed June1-June30, then June15-30, then disappeared.
Got a surprising call from SA yesterday... SD Carlsbad location, they had a identical car except with Cream interior and ask if I wanted to take it. Short answer, went to see it, switched my order and took delivery yesterday. They told me they got 6 plaid yesterday (one was the one I got, another was was black (also cream with CF), another one that was white (don't know interior), red (don't know interior) and 2 others. This was supposedly the second shipment, one of the managers there got the first shipment a couple days ago.
