So with some encouragement from Edgar, I got my seat bottom replaced. (see his restoration project in this thread below)

What a PITA! I prefer mechanics rather than seats, door panels, headliners, etc.. Anyway, the cover is awesome, looks great, perfect match to OEM, seems to be high quality leather, definitely recommend it. I bought my cover from ebay seller u.s.autoseatcover. Mine is leather, dark charcoal, code 692. The original seat wasn't that bad but needed to be replaced.
A couple of tips, take the seat out, don't even attempt to change the cover with the seat bolted in. Takes an E14 and E20 socket to remove. And once the seat is out, take the two 13mm nuts off to remove the seat bottom from the seat (remove from underneath). It has 2 plastic clips toward the rear, and 2 nuts towards the front. Gives much more room to work. The only negative on this cover, the electrical switch area is not pre-cut. My plastic trim was already broken so it was hard to tell exactly where to cut.
Either way, do it, don't wait, and I definitely recommend the seller on ebay.
Now is a good time to clean under the seat. Mine was nasty!
Now I need to find a replacement seat switch trim piece to replace my broken one.
