If you are talking about the "monroney" label (window sticker) which shows the original sales price and features of the car, you need to contact Mercedes-Benz USA and request a copy. I received my copy from MBUSA after sending them a letter with the VIN number of my car. The document appears to be a photocopy of a microfilm file copy. In other words, it is readable but not very clean. Try the MBZ website for contract info at:
