A lot of good ideas here.
Speaking of hardware only upgrades/changes. Is there anything that would make you consider trading in your old Model 3 for a new one, or make you regret you didn't wait to take delivery?
My list is:
Range: 400+ mile EPA range 2170, or 4680 doesn't matter how they get there.
Charging: 10% - 70% & 70-90% in ten minutes. So 20min gets you from 10% to 90% or 320 miles
An HDMI input for the center screen would be nice, along with a integrated power inverter. for PS5 or other consoles
Ventilated or A/C seats with massage.
Adaptive air suspension.
Sirius XM module. Option that installs like home link. Also, mini mobile Starlink option
Lithium 12v battery. Edit: Zoomit beat me by 2 minutes! lol
powered frunk.
Active noise cancellation (just need the mics in the seats and the rest is software, right?)
Better paint with more color choices.
