I replaced the license plate holder with a nice clean design high gloss stainless frame, which goes great with the car's silver colour and replaces the advertising plastic plate holder which was installed by the dealer when the plates were first put on the car. When I removed the old plastic plate holder I discovered that the dealer had simply installed the plate and holder with metal type self taping screws right into the plastic bumper - there appeared to be no special mountings or clips. Is this standard procedure? - just screw right into the bumper? The concern is if it is done this way a few times the hole left by the screw will simply have nothing left to hold the screw.
