You can get the 3m stone/chip guard put on them. It should come with the installation if you get it on the car. This is the clear vinyl stuff.
Sorry that I wasn't clear....I'm thinking of the black vinyl, maybe carbon fiber ones....My Wife has a set on her Miata and they really look great....not to mention the protection. I checked with the Manufacturer of her's (Colgan) and they do not offer them for '04+ Prius....They have them for many other later model Toyotas, just not the Prius. Does anyone out there know if the Camry or Corrolla side mirrors are the same mirror as the Prius?
