I don't think the S-Class is some amazing design exterior wise. Its safe and predictable. Without the sport package it really lacks to my eyes. With the E and C class looking identical, that doesn't help. In regards to proportions, my goodness they did nail it there. No confusing this is a big time luxury car. No SWB here helps. The S/7/A8 are handsome but predictable. The Quatrroporte just missed the mark. The Panamera is really sporty and a hatchback. I think there is significant opportunity for the LS if its a design knock-out.
