Have not seen too many threads on the drive dynamic seat option. Have it on my E500 but cannot really feel the supposed changes in the seat that much. Is level 2 supposed to be more pronouced than level 1 ? The pulse function is kind of nice, especially on longer trips.

I test drove an E500 Sport (owned by DiabloJoe from this board) and could definitely feel the changes in the side bolsters when taking a turn - I thought they were fantastic.

There have been mixed reviews. I have spoken to many people including salesmen who talked me out of it. They said that unless you are a very aggresive driver the dynamic seats are not that useful. They also felt that the regular seats are so good that even the multicontour seats are not worth it.
