I put a hitch on my Mercedes E350. It's nearly invisible, and came complete with the electrical interface that keeps the computer happy. Highly recommended.
Here's the link for the ML hitch:

I was quoted $3,500 to $4,000 by the Mercedes Benz dealer to install a factory tow hitch on to a ML 350 Bluetech 2011! I was wondering if anyone else had this happen and if so, where did you go to have the work done and were you happy with it? I live in Southern Cal.
