I've been watching carefully and have yet to see another F15 with these wheels since buying mine. Perhaps there is a certain rarity to consider. I have been surprised at how clean they stay, and with the CEO enjoying time in the driver's seat more and more ("Honey, why don't you take the 4 to work so I can use your X5"
), and liking all those spokes, I'm just going to let it roll for a while.
