Update - I ordered my SR+ on 12/4/19 white on black with Aeros. Verbiage at that time stated I would receive delivery by EOY. I had a delivery scheduled for 12/28/19 (no VIN), which was subsequently cancelled the night before with no explanation. I failed to receive a car by EOY. In early January I was told it could be weeks to a month before my SR+ would be ready. As a result, I had my SR keep a close eye on inventory that became available and he was able to match me to a white on black LR AWD last week. Since Tesla failed to deliver by EOY, I have been hounding my SR for information re: reparation on the tax credit nearly every few days. He did say that Tesla was approving credits on a case-by-case basis, as long as the customer ordered before 12/8/19 (which I did) and was available to receive their car by EOY (which I was), but couldn't guarantee anything. He kept dodging and giving vague but somewhat positive answers, no commitment though. Even when I matched to the LR VIN, he said he couldn't guarantee any incentive. I scheduled my delivery for tomorrow anyways and continued to ask for the credit - tonight my MVPA was adjusted by $1,750 as a "Referral Credit". Pick up tomorrow. What a roller coaster ride.
