How do you know that headroom will be as good as the C-Class?

Any specs to compare the both of them or anything else to go off of?

-Front Head Room: 37.0"
-Rear Head Room: 35.6"
-Front Shoulder Room: 56.0"
-Rear Shoulder Room: 53.2"

C-Class:
-Front Head Room: 37.1"
-Rear Head Room: 36.9"
-Front Shoulder Room: 54.7"
-Rear Shoulder Room: 55.0"
