opinions on bmw bottle caps?

i was searching on craigslist and found some e30 bottle caps for $125 for 5 wheels and tires with 80% tread left i got to texting the guy he still has them and said he'd take $100 for all 5. now the question is are they worth it and what would be a good color to paint them even though my car is mix matched color right now I'm thinking gold or black or white.
