I was told they do not work on Dodge purchased Sprinters AT ALL by a very haughty service rep. I talked to his superior and they did an about face. However, they do not do warranty work. OK...no problem. All I needed was an oil change. Imagine my surprise when they charged me $300 for the change!
I've heard very bad things about this dealer. But I like to form opinions by myself. This experience supports what I've heard. See for yourself, but be warned. These guys are not to be trusted.
