I was going to get the covers and have them painted but heard that it doesn't fit 100% correctly at least the PUTCO chrome ones. Anyway, I am looking on car-part.com and want to make a purchase but I'm not sure as to what the Autodim feature is. I know my mirrors are heated but not sure if the auto-dim means the tilt mirror? Please someone who knows give me an input because like I said I need to purchase ASAP. Thanks in advance.
