I'm in the market for a used M3P with FSD. How do I tell the difference between what's on the car: the full FSD upgrade ($10K) or the monthly subscription ($200)? On one of the cars I'm considering, the software screen does say "Full self driving capability: Included Package", and does not mention any date for auto renewal or expiry. Does this mean that the car has the $10K upgrade enabled? Thanks in advance!
