When I learned that my 21 year old car qualified for road side assistance, my jaw dropped. I went to the MBUSA web site and there it is. All Mercedes in the US regardless of mileage, age, or number of owners, gets roadside assistance. Granted if my car needs to be towed, there would be a charge but at least I have one central number to call no matter where I am. It's like having AAA for free, just for owning a Mercedes. You have to love it. This is what I call real customer support.
