Does anyone have an opinion on dynamic multicontour massage seats in 2000/2001 CL500

I'm about to buy used one but not sure if this is an option I need to have. It seems to be different from the air-conditioned seats.

Used to have 2000 CLK with multicontour seats which allowed near perfect seat comfort.

All views appreciated!

The Dynamic seats are different than the "massaging" seats.
