You are comparing apples and oranges, montlhy payments and yearly payments. "$800 a month, another $80 a year". How about being honest, "$800/month, another $7/month"?
>> FWIW: I've purchased or leased various BMWs and Audis over the last decade, and have rejected every offered subscription plan for pushbutton concierge, car wifi hotspot, etc., and have regretted paying more than $0 (on a one-time basis) for BMW's older iOS integration product.
Who cares about what you did or did not? Looks like you are here to congratulate yourself. Why would that matter to anyone other than you?
Or maybe you were stretching to get the car that you cannot afford. Who cares about adding 1% or 2% of the monthly price for something that is useful? Among people that buy luxury cars (myself included) I've not seen that. You need winter tires? Could be several thousands. Nobody blinks at $7/mo. I don't think you have been honest here.
At hand is the question of whether a buyer might reject paying $80/year to BMW USA in order for one bit to remain in the 'on' position to enable CarPlay--not provision of cellular service or anything further.
My suggestion is that not everyone says "oh, the lease is $800 a month, another $80 a year is fine." $80 is still enough that being charged $80 for a pencil, or a chicken sandwich, or whatever, would be outrageous. And leaving a bit flipped is incalculably less work effort than preparing a chicken sandwich.
