It depends on the model year. Mine is the 4h 2016 version, and at that time (IIRC) the model 3 didn't have the MMCS display, just a basic radio, and lesser alloy wheels, non metallic paint, no electric heater (you needed the engine running to warm the car). The 4H had all these, plus a sun roof (yay!). The 4HS had the lane alerting and 'intelligent' cruise control, and the 5 (which possibly came out slightly later) was all the bells and whistles (and beeps!) plus a higher trim spec. But that doesn't hold for models in later (and earlier) years.
