I've got a hole cutter around here somewhereNo hole on a W209 so you are stuck with the flat badge.
I think traditionally, the MB's with sporting pretensions like the CLK and others, are given a badge in the radiator grille to differentiate them from other MB models. Fitting one on the bonnet might look rather odd above the existing one on the grille. Russ
