The standard XLT rims are machined, which is much shinier than painted, but they are not polished, which results in an almost chrome-like level of shine. The optional 19s are polished. On my price comparison site I equate machined with regular aluminum wheels, while polished I equate with chrome. These wheel comparisons are necessarily crude, though, as there are many different grades of finish. Many chrome wheels these days are only "chrome clad," meaning they have chrome-look plastic fastened to them.
