Faded black trim can be restored. You won't believe how bad mine was. All I did was coat with Zaino tire dressing.
Makes the bumper trim so shiny it looks like paint and the sides so black it's stunning. Of course, if there is wax residue, use a rubber eraser to get rid of it first.
In regards to front grill.. there was a discussion earlier. Started by Gayle, I think? Anyway, you CAN paint it in a pinch, but you need to sand it down to ensure your new paint doesn't look just the same afterwards. On that note, I just bought a new front grill to paint instead
Lucky for you, the car is black. Black is difficult to mismatch... I like white as well. You can get away with minor deviations without issues.
