You may not like it, but its actually smart. It makes zero sense for them to NOT deliver these cars with the spoiler if they have them, because every single one would then need a SC visit or ranger visit to do it. Why create a due bill item if you dont have to?
I say this as someone waiting for their spoiler, as well. If I have not heard from tesla in a month or so, I will reach out, hoping that by then they A) have stock, and B) know exactly how to put them on so I dont have to worry about gaps, lifting, etc.
