I agree with you about the infotainment system. I went for the SE 4 years ago because of the parking sensors and electrically-adjustable mirrors. I like the main beam assist and extra safety features, but these were not must-haves.
the S has electrical adjust mirrors for driving position, just not folding in and out or heated
plus the S has real volume and select knobs as well as the steering wheel controls and not a slider on the touch screen on the SE
i have the S and got it because i didnt want all the extras i wont use and when i drive an SE when i take it for a service im glad i got the S over the SE
i would like heated mirrors like all my cars since 1998 but it isnt worth the extra and i dont mind wheel trims so that does not bother me but it might bother you
and its even very small things like the SE has silver paint around the a/c dials that will wear away and look horrible over time where as the S is just black plastic
and as mine is a 68 plate i have the deep boot underfloor so if its newer it is shallow under there so lift up the boot floor and check and that is for all trim levels of 2019 on cars i think
you still get rear electric windows and rear disc brakes on all trim levels painted mirrors with integrated led indicators
