"The best or nothing" is MB's marketing slogan. I think it's great. I like Audi, BMW, and Porsche as well but still think MB has unrivaled cachet, and for good reason. There was a time, not too long ago, where people wouldn't touch Audis. It was viewed as a dangerous, second-tier, "luxury" Volkswagen. BMW has always been a "driver's car" but only recently came into its own as a luxury make, same for Porsche, if not more so. MB has always been the luxury standard. And AMG is hard to beat when it comes to performance.
