Of the two photoshops... definitely the one that retains the chrome (takes the focus off the bow tie).
But in all seriousness, I agree with the plain grille. If you cut the current mesh out of the holden grille you have, you'll be left with a nice frame to fix some black mesh to. Keep the tension on the mesh while you fix it up and it should look mint.
I'm going to be painting the whole grille gloss black (including the badge), in a similar vein to the front end of new-gen audis. It will be a subtle difference to the matte black... but where the current matte black grille is lost in the colour, the gloss should make it stand out and be more bold. I'm talking merc-spec high-gloss solid black.
