Yeah.... pure aesthetics

They are just heavy duty yet relatively inexpensive rims for winter that my Swiss mechanic uses for almost all his SVX customers. You'll notice in one of the pics that the silver SVX has the same rims for winter. But then you can get all sorts of cool hub caps. Except that ours aren't anything special. I'll take another pic as soon as I find ours and put them on. They got misplaced during our latest move but I've gotten it narrowed down to a 150km radius
