How about a newer one?

I have not been in a newer S600 until recently and don't know how much more you can get out of a sedan. I rode in the back seat for 2 hours and didn't want to get out when we arrived, when we returned the seat heaters warmed within a couple minutes...if that. It's hard to judge performance without driving it but it seemed like it would do anything it had to do in an effortless manner.
