AUDI??? Really? Can you name an AUDI that have the interior switches of the same level with a W221? Lets just compare some of them:
Despite the fact that I really love the D4 interior, it's not even close to W221 in terms of small details. Every detail in a W221 was unique, not seen in other models. They were very well made and there was a feeling of quality. That's what I call attention to small details. I think W222 is the best in terms of the overall interior design, but have some flaws for which I see no excuse. But the small details are still there. The thing how they integrated the climate buttons into the design. It's just genius!
As for the vents - it was ok back then with that "loaded" design. W223 has the new clean design with the large areas of clean almost straight surfaces. So the vents are out of place there for me. The car of the future cannot have the vents from 80's. They should have asked AUDI, BMW and Bentley how to do it)
