Looks pretty clean. Do you have some money to burn? i could throw out a few suggestions:
1. Drop it! H&R Springs + Bilstein Shock combo for a more aggressive look. Another option is to get KW Coilovers, but that's a bit more costly.
2. Amber or clear corners for the turn signals
3. Avantgarde grille, if you don't have one already.
4. Window tint all around
5. New wheels? That's preference though.
Aside from that, the car looks like it's in decent condition, I like all forms of w202 unless it's riced out. like mine.
