Might I offer a compromise on the trim?
Bumpers you can take apart on your own, no need for a body shop. So pull the rubber pads off, plastidip it, then put it back together. Saves money and very reversible should you later choose.
Headlight bezels and grille buy a cheap set with flaking chrome, scuff, and paint. Nice chrome parts are getting harder to find and not economical to replate.
For wheels don't bother with aftermarket or repop. Find pontiac firebird gta 16x8 front wheels, repaint the mesh, then polish the lips. Factory made them in black, grey, and gold. It's cheaper that way.
