Today I saw very nice looking grille block made of smoked polycarbonate, seemingly made by some aftermarket company called HEKO. Quick googling showed they reside in Poland, but maybe they will ship overseas or have a dealer. I haven´t checked. They make grille blocks for some european cars /VW, Skoda, Renault. - have a look:
