Tbone85 5pts The summary of this article indicates that if you want to pretend that you're driving a large sports sedan then get the Benz. If you want actual performance, then the Porsche is vastly superior. I agree, there seems to be a strong effort to rationalize away a huge performance difference. If you don't like the way the car looks, great. Just don't pretend it makes sense to test a performance car in comfort mode to justify your aesthetic bias.
