So true! Tech where it never existed before. In the '70s you could buy a side mirror to bolt onto driver's door or fender for $15 and put it on with 2 screws - do it myself for inflation-adjusted $90. Last summer someone clipped the driver's mirror on our 2020 minivan in a parking lot - it's motorized, has defrosting coils, and is molded into the door frame & side window. No way to repair myself with auto parts store generic. Body shop bill = $900!

Similar for all body parts given modern design - even the non-tech parts are more complex is size & design, of more expensive materials.
