I think the interior looks very nice based on images. I have a C250 coupe which has a very similar interior
and if the CLA is anything near, the quality is very high. Did noticed some of the CLA dash control buttons
are made out of black plastic instead of matte silver in my C-coupe.
The high window sill, narrowed windows and low ceiling, I think, makes the interior, especially in black,
feels a bit claustrophobic for the rear seat passengers. The panoramic roof, while smaller than the full length
size for the C-coupe, allows light into the cabin hence reduced the feeling of being in a small dark room.
