For anything for your car in general, as users of this site we should first check FastLane (see the link above) out of respect for the wonderful hosting of this site. If they don't have it then....

I think it's OK to share a link for a site that specializes in this kind of thing (I'm not sure if it's against the site rules to provide such a link, if so feel free to delete my post).

But the following folks are the king of Mercedes upholstory. They have everything from replacement center consoles to extra MB-Tex (though I don't know what your console looks like and if you can graft it onto there, ask them, I've used it elsewhere in the car), to things for the roof (seals, etc)-- you name it. You can also call them on the phone and they will try to help if the website doesn't have the info. They also sell spray paint the color of your interior. Here is the link:
