I couldn't answer every question on you're list, but I will tell you that Mercedes-Benz has always let the car market when it comes to advanced safety features and innovations. I'm not saying that Cadillac hasn't, but Cadillac isn't know for innovations. They're known for style and the "you've made it factor". Mercedes has always been known for the above.

Chad might be able to answer some of you're questions on S-Classes. He has a '99 W140 S320, which I've been told is one of the most over-engineered cars ever produced.
