I am searching for a used s class (non maybach) and would like to find one that has the massage feature that also includes rear seats.

When looking at specs, what should I be looking for (certain years, trim, or package) to identify when rear massage feature is present. A lot of listings show multicontour massage seats as a spec but none i have seen specify whether rear seats are included.

Thanks in advance

It must contain the code
406 Multicontour rear seat

In the us you would need to find one with the executive package.
