Looking for repair shop in seattle or in renton for my 99 230 slk, or should I bring it to mb dealership in bellevue or in seattle. I just brought my slk to a shop in renton, all they did was looking up code and charge me the hrs fee. They told me that they can't work on it, and refer me to the dealership even though they specialize on the older benz mine is a 99, I thought is enough that they can work on it. The check engine light is on and won't pass the emission. Suggestion anyone?
