We drove our first sprinter for 75000 miles and never had to have it towed. We have not had to tow our newer one yet as well. There are now more Mercedes dealers who are sprinter dealers and more are being added. I have heard before on this forum how nice it was when Dodge dealers serviced them. That was not our experience, many Dodge dealers did not service the sprinters and my experience with those that did was not very satisfying. At least three dealers we used only had one sprinter technicians per dealer and if they weren't working that day or loaded up we were out of luck. That is not the case with the Mercedes dealers we have visited. However as David said if you are concerned don't buy one.
