There is a hitch for the W210 E-Class. Last I check the Dealers did not have it. Go to
www.hitch-web.com . The 1-1/4 inch hitch is made by Dalan model number DA24729-C13283. The rear bumper has to be removed! I called my local U-Haul dealer and they said they can order it and install it. Have not done it yet. I may need a 2 inch hitch.
