i've had a broken driver side mirror for over a year now, its being held on with many layers of electrical tape. the cost will run you from $30-$145 depending on if you get it at ebay or at the dealership. I highly suggest NOT getting it at the dealership. Even thoa its new, if your car is over a few years old the paint wont match due to what the sun can do to your paint. A body shop will do it for like $50, so if you do the whole thing on ebay your lookin at like $100. If you can find one in your body color then thats even better.
