At the risk of betraying my ignorance, am wondering if anyone can tell me whether the seats in a 92 300E are leather or vinyl. Had always assumed they were leather and have been using leather cleaners and polishers on the surfaces. My doubts were awakened when a friend expressed disbelief and puzzlement to find vinyl seats in a Mercedes. Told her I was sure they were leather. But after closer examination and a reference in this forum to 'MB Tex,' I'm wondering if in fact, despite the distinctive smell, the seats are all vinyl or at least mostly vinyl. If that's the case what do you use to keep them clean? Perhaps that's why they've worn so well in a 10 year old car?
