This really looks like a corolla. I’ve heard the critique before of the interiors but wow. Beyond that, they have to roll the windows down every time you open the door to prevent damage to the seals? That seems insane? I’d get used to it but I’m surprised this isn’t pointed out more often as kind of absurd engineering.
Not sure I understand your concern here, but isn't is how every frame-less car door works? See https://www.youtube.com/watch?v=7NM-dunSOLw
So it’s a form over function trade off. CLS is a low volume model. Looks absurd to me in a model 3 “mass market car” alongside 2 door handles, a classic one and a cool button press one.
It isn't. My 2004 toyota solara had frameless windows and didn't play any shenanigans with it, and as others in this rough thread have pointed out, subaru doesn't either. I don't know where you got this idea but you've managed to ingore two very popular brands at minimum so maybe you should reconsider some things
In the case of Toyota Solara, how does the glass fit with the seal on the A-pillar and roof? The roll-down mechanism is required because the glass on those doors have to be "inserted" into the seal.
