WTF-I am pissed off. No other fellow E30 M3 owner should go though this shit. I am now going to be very cautious as I too have a Diamondshwartz 90' M3. It takes some work to get into those cars if you use the deadbolt. I hope you find it and I will DEFinitely keep a look out!! I can spot another E30 miles away. Best of luck to your friend.
