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.

I bought a Mercedes SUV a few months ago and I negotiated installation of a tow hook as a part of the deal. It still cost me a lot to put the tow hook in but not near the $3,000 quoted.

To put a hitch on a Mercedes SUV there is a lot of work involved, both mechanical and electrical while the option at the factory costs only $500.

I talked to a few people and I decided not to even try the aftermarket route as some reprogramming of a computer was also required.

On the plus side the vehicle is the best tow vehicle I ever had (other than the motor home). It is unbelievably stable, feels very solid even towing 18 m glider trailer.

I suggest find a deal who can do it cheaper. Call around. Find one that is less busy.
