Factory 8-hole question

Hey guys. I have a question. On the contrary to other W124.5s I've seen, versions such as the one in the first picture, their 8-hole factories seem to be alot more shinier than mine, as in they look like they have the sort of stainless steel shiny look and when I hand washed my car mine seemed to be a bit dull...up close the looked like they were pretty worn, that is they looked scratched, like somebody just took sand paper to them, though not as extreme...I tried my best to portray what I mean with my car vs the other example. How do I make my wheels that shiny? Do I have to buy new ones or do I have to get them fixed or something...

Your help = strongly appreciated. I'll try and get some better pictures regarding the condition of my wheels.
