I can confirm as I too own an MS906. The MS906 includes the 38 pin Mercedes adapter so no need to buy anything additional. The MS906 is around $1300 though so more on the spendy side, more of an enthusiast tool than something every w210 owner should have.

I also have one of Autel's smaller consumer units, I can't remember the model number but it was inexpensive at around $200. It works with the w210 but requires you to purchase separately their "intelligent 38 pin adapter" which is $150 more. Note you must use the more expensive "intelligent" adapter that has a black box hanging off it. Their lower-end diagnostic tools won't work on w210 with a passive adapter.

It's only generic emissions related codes via OBD2 on the w210. No transmission, no ABS, no airbags, nothing else. Emissions-related engine faults only. And generic codes only; nothing that is Mercedes-specific or Diesel-specific. Ergo, the OBD2-only diagnostic tools are pretty much useless on these cars.
