Sure bro. I made that mistake buying a sticker before for $3 in ebay. Looks crappy with the break dust, dirt and road grease cause Im nitpicky about cleaning my rims and roundels when it gets dirty. Car wash, and wiping them regularly with rags makes the caps look "older". I prefer "new shiny" looking BMW wheel caps.
When I got these new center caps, you know that it came with those peel off clear plastic covers- now what I did was, I took those plastic covers off cause they have bubbles in the middle and stuff, I cut a saran wrap in circle size half an inch bigger than the caps and stretched coverered each caps with it. Guess what, every time it gets dirty, I wipe it with a rag and its gets so CLEAN, it looks so "shiny" brand new! its been 4 months now since I had it. Wheel caps that looks new, with my own version of clear bra. LOL
