A quick one:

I recently bought some blue-checked cloth front seats to match my car's back seat (1985 635csi). Previous owner had been using unmatched E28 seats and they were pretty rough condition.

Guy selling the matching set described them as "M6" seats, which was perhaps stretching the truth. Nevertheless, the cloth is in pristine condition and they a perfect match, and they complete the interior.

However, being used to BMW electric seats from E38 & E34 can someone confirm: what is the middle lever adjustment aiming to achieve? Maybe mine aren't fully function; but the middle lever sure seems to provide "minimal adjustment", perhaps in that "M6 seats" sense, I fear.

PS: not forum discussion material, but if no one minds: looking for a couple of knobs/lever surrounds from side of the seat backs if anyone has some scrap seats they'd like to sell a part or two from. Maybe the joy of finding that perfectly matching cloth in good condition did overwhelm my senses!!
