I’m planning to purchase a model Y with FSD within a month or so. I figure buying FSD on it’s own after purchase of the vehicle will save on registration/taxes for the car (NC resident here) in subsequent years. So does it make sense to put less down on the car (w/o FSD) then buy FSD afterwards? Could also earn rewards via credit card too. Does this affect insurance with $10k in “value” missing from initial purchase? Guessing probably not.
