My research on here indicates that it depends on the year for your car. My 230SL had a little piece of MB Tex sitting in the box that I threw out since it was in very poor condition. Later cars came with the carpet piece. I don't think this is something that people generally care about very much. If you really want to spruce it up, consider one of the nice cupholders made by a few of the vendors on here. I had one made recently that I'm very happy with -- looks OEM and fits wonderfully. Some owners also get little matching coco mat inserts, which does look very natty. I'm sure one of the more experienced members can give you a year breakdown on what's what and when.
