Does anyone know where someone could pick up a repair manual like the haynes manuals which tell how to do everything to anything.

If your question is related to Haynes vis a vis your Benz, the answer is no. Aside from the factory issue, the rest of the shop/repair manuals pale by comparison save for the usual, weekend mechanic chores related to basic maintenance and chores.

I've used (for years) Haynes, Bentley, Chilton, Clymers, Motor, Mitchell, All-Data... for various vehicles. The most detailed has consistently been the factory shop manuals. I will concede that the aftermarket manuals may, on occasion, provide a photo or clarification which supplements, in description, where the factory manual is less than clear.

To paraphrase Samual L Jackson in Jackie Brown,

"The M-B Shop Manual: when you absolutely, postively gots to fix every mf job on your car.....there is *no* substitute".
