>A Model 3 built today has less features I have a 2021 TM3 and I don't think it has. - heatpump for one makes a major difference - LFP battery is great (available only in SR+) - powered lift trunk - double pane front windows - wireless charging trays (a simple thing, but very nice) - USB-C ports (and the drive can be mounted in the locked glove box) - Ryzen CPU - matrix headlights (not sure if this is true in US) - outer (pedestrian awareness) speaker - magnetic sun visor clips - depending on location, the build quality is also much better now I'm surely forgetting/not aware about more changes. And that's not counting the many improvements that came in software updates, which of course you now have as well, but they were not in your car when you bought it in 2018. E.g. sentry mode.
