Yes, that is one of the complaints you read/hear about the Corolla (and some other cars).
I understand the point although I personally don't mind as I almost never put my elbow on the upper-door part : I'd rather have all parts of my body inside the car.
But I remember doing it more frequently in another car which had a too-low door armrest for me.
And in these good (?) old days (Datsun), the upper part was pure metal... Boy am I a survivor !
And the ceiling was pure cardboard. Now manufacturers pad those also (and the Corolla has some nice material there).
Not because we touch it, but partly for sound deadening and mostly for appearance. And appearance sells.
What was the most read/heard complaint again about previous gens Corolla interior ?
Oh, yeah... that the dash was hard plastic...
