Pretty sure Mercman had a rolled C36 with black leather in it the last time i popped over.
They also had a couple of nice cream leather interiors and at least another grey one, all still sat in cars. They could all be gone by now but worth a shot...
Could be but even then theres the seat pad sensor issue which IIRC differs between the pre facelift and facelift seats as connector is 2 pin vs 3 pin on the facelifts or something like that.
