Looking good. Are you going to do an Evo treatment? Go for a stock look or more of a show car look? I see the smoked rears and the M Parallel wheels so I'd guess you're going modern. Some Group A mirrors too?
I had an '88 E30 M3 and thoroughly enjoyed it. I had my one and only personalized plate on it: "ORIG M3".

Still have the plates in my garage. I hated when people asked me about the body kit on my 325.
