Nice looking car...
Look up
www.leatheriquecanada.com for those leather seats... working on my set of seats right now with similar cracks... don't over sand the seats like I did though! I'm sure they'll turn out great.
Very similar to my 325IS, and I have to give a +1 to Alex at ACP, great guy to work with, he bailed me out on my project which included everything from fixing some body damage from the previous owner to replacing the gas tank. Also working on a track car project with him.
He has a facebook group page:

Anyhow, let me know if you're looking for a certain part, I'm sure Alex can help you out too, I have 4 E30's in pieces in my basement though
later,
