I have 16" steel wheels on my '06. Back when the wife drove it, she lost a wheel cover. I picked up a used one from eBay for $65(ish). In teaching her to drive, my daughter curbed a wheel, needing a replacement and I got aftermarket. It looks and functions identically. The only downside is that the Toyota logos are missing from the aftermarket ones and I wasn't motivated enough to unglue and reglue the old one.
