Vehicle fascia assembly includes a plastic fascia panel and a grille frame. The fascia panel has a grille opening defined by a flange extending rearward from the show surface toward the back side of the fascia panel. The flange has a plurality of flexure fingers at spaced intervals along the flange. The grille frame has a forward facing show surface and has a C-shaped channel molded around the outer edge of the show surface. Upon the assembly of the grille frame onto the backside of the fascia panel, the spaced apart channel legs fit onto the flange and the flexure fingers are biased and then engage with an abutment face on the grille frame, thereby attaching the grille frame onto the back side of the fascia panel without exposing the show surface of the fascia panel to injury by the grille frame during the assembly operation.
