Neil:
Click on 300E in my sig - I have a front view of the matte black grill. When/if you paint it, do consider using the strips from a 98C class instead. they install like the strips that came with the car instead of with the plastic clips MB uses on the 300E replacement strips. I just ordered them for mine, no pics yet on the matte grill, but there are some at the link below on the gray grill.
