Thanks guys. Did it before on an old Oldsmobile I had years ago... wasn't so sure on these newer Benz's if there were any hazards. I do have a little "pad" on the jack base to "cushion" the contact point.
Looking forward to contributing and following the MB forum!!

I made a stacked block of plywood that fits on my floor jack that contacts the suspension crossmember between the diff and the spare tire housing. This 2" deep x 10"wide area is ideal for jacking up the whole rear and the load is spread over a wide area.
If you need a pic of the item I made I can post later
I am not a fan of hoisting the car by the diff especially on a IRS as the housing is not a robust as in a solid axle like found on a pickup truck or older American car. By lifting on the diff and all the pressure concentrated at a small area you could risk cracking it or having leaks on the seals. I am not sure what the material our diff housing is but I assume it is aluminum and probably not that thick
A risk that i would avoid

Take a look at the pic below -
Red circle is where I usually put the jack to raise the rear end (with a 2x4 piece as a buffer).
I believe Boom_vang is saying he places the jack where the green circle is.
Diff housing is NOT made of aluminum[on a W203].
This picture was taken in the midst of a snow storm in New England area; hence the bottom was very dirty.

Yes that is the spot in green where I lift from
looks like the diff is only attached at one end, hence lifting with that could put unnecessary stress at the mounting point
