There is a lot of information on the site about interpreting the numbers on the plate under the hood, for getting the data card from the MB archives, and for interpreting all the numbers on the data card.
Use the search function, limit to general discussion, subject line and use "data card" as the search item. Also try "data plate" to get information on the plate under the hood. The main items here are the paint codes (body and top) and the body number (different from VIN, that matches up with the numbers stamped on the hood, soft top lid and hard top. The threads will explain.
