We replace mirrors all the time. Most often they get broken in tight parking spaces. This one is unusual in that it got hit by a motorcyclist. Don't be embarrassed if you broke your mirror backing out of your own garage. You are in good company!
Replacement parts including mirrors almost always come unpainted. We have lots of customers that plan to install mirrors themselves but need paint. No problem! We're happy to paint parts for do it yourselfers. Occasionally a car manufacturer will offer pre-painted mirrors. If you are lucky enough to find one, buy it! Even if it costs a bit more, it is usually cheaper than buying a mirror then having a body shop paint it.
Final word on mirrors (and all car parts): make sure you know what you need. You'd be amazed at how many variations there can be for a single year and model of car. The sport model looks different than the luxury and economy models. Installation and connectors can be completely different for manual vs. power, heated, memory, integrated turn signals & lights, blind spot detectors & cameras, self-dimming, folding and non-folding. . . you get the idea.
