If I remember correctly, if you took delivery in the last 3 days or so of 2020, you got the FSD preview for 3 months. I remember this because my M3P was damaged on Christmas day before delivery, requiring repairs and a new delivery on Jan 1. I was pissed that I missed the cut off date, so I emailed Tesla, and they agreed to still honor the offer.
Anyway, here's hoping the do another EAP offer this year like last.
