The cognac interior (code 250 I think) has a brown square-weave carpet in that year, I think. The Meredith book, which is a pretty good source but not infallible, says the carpets were 8008 brown and the headliner was 8038 bamboo. This is what my car, which has its original interior, seems to have. Interestingly, cognac 250 was also available in tex, which would give you the best of both worlds, but I have never seen it. Mind you, I haven't looked at that many SLs.
