One set is driver quality. The chrome isn't perfect, but the centers are all dark red, not faded. The paint on them could stand to be re-painted so they are all uniform and match your wheels. I can provide info on how to paint these to match your wheels.
Below: $20 each, or 80 for a set of 4. See the pics below:
Below are the caps that have very nice chrome, and nice dark red centers. They also will need to be sprayed in your color of "argent" because of color variations thru the years. If your wheels have never been painted, you may be in luck, but otherwise, expect them to not match in color.
These are my backups, and due to their condition, the price is reflected in the quality. $50 each or $200 for the set.
