I think the MB interior looks naff, more like going to somewhere like Sound Gallery in the 80s and throwing every new fangled piece of LED lighting at it that was named 'cool blue' or similar. Over time I think it will age really badly.
All the new generation Audi’s have the same lighting, as do all the new generation BMWs it’s not a Mercedes specific interior option.It’s all the old generation models that don’t have it. I personally like it, and in the Mercedes you can have as much or as little off it lit up as you want.
