I'll jump in. I have an 06/2020 MY and am considering a new MY to get HW4. I am torn, I will lose the silent drive under 25 mph, but will gain HW4, heated steering wheel (no big deal since I can preheat or precool the car), heated mirrors, front and rear castings, plus everything else that has been fine tuned in the last three years.
Or do I wait for the refreshed MY? The only really compelling thing in the refresh I would like is perforated heated and cooled seats. Air suspension would have been nice but... And I would have to purchase FSD again.
