Me and you have the exact situation. I put on hold a 2018 M3 white on white with 38k miles For $32,xxx. Found out it didn’t have FSD. Later switched to a different white on white M3 with 7k miles for $39,xxx that had FSD in one of the photos. While doing that the car specialist said before you switch just so you know, this will not have FSD. Look at screen shot above. Long story short, I cancelled and ordered a new one from Tesla.com for $40k without FSD.
