Just ordered Model 3 last weekend in Costa Mesa, CA. They said it will be a 2-4 month wait. Is it really true? I don't want to have it delivered on Jan. 1, 2019 and not receive the $7500 Federal credit. I got midnight silver, RWD, no EAP or FS, 19" tires. What are my chances of getting it delivered by end of the year?
