So i was just looking through all these threads and noticed this and realized i have all of my interior Carbon leather trim as i replaced it a while ago...its sitting in boxes all wrapped and ready to be shipped out. I have a Jerez Black E90 M3 so this is the exact trim you are looking for.
I have no idea if i am allowed to PM or not since i have not been able to post in a while.
email me at firstname.lastname@example.org
if you are still interested.
