I'll chime in a little late here with an opinion...front grill inserts are no longer new and different. They've been out for a long time now. In fact, our local autoshops, Craigen, Autozone, etc., carry stock on a few popular models. WHen that happens, I put them in the same category as curb feelers and spinning hub-caps---people put them on only becasue it's what they find while roaming the aisles of the local autozone, not because the trucks design screamed the need for it. Front grills are on there for the sake of being on there, and that's a bad reason to put them on. They're not special looking or anything, they just look like a 1984 cutlass sierra with fake spinning hubcaps, 5 telephone antennas, and 12 reflectors! If you look at the Armada front end, there's already a lot of chrome up there, the design is not in need of more.
Sorry to rant, but you asked for opinions...
