You can get the part at a discount from Circle BMW:
Circle BMW You will need to pick the trim from the column on the left of the Circle webpage to view.
Note: The trim kit works for all 325 2001 and 2002 coupes and converts. But only 325 four door sedans up to production 8/01. (330's come with the trim standard. This kit will work for the M3)
If your 325/M3 headlight assembly does not look exactly like the one pictured in the above link, then you have the new trim design. Unfortunately, as far as I know, a trim kit is not yet available for the new design.
You can check my post in the DIY forum on the trim install:
