If you are in Los Angeles, Check out Mr. MB Motors in Tarzana. he is a very good mechanic.
Look in the good mb shopd section on this discussion forum for a shop in your area. check the search function of the site as well to see if you can find some help for the problem.
Sounds to me like you don't need to send it to the salvage yard if thats the only problem. These cars easily last for years and years.
If the car runs good otherwise, it should be fixable.
