I know my mirage currently has no major modifications for mpg, that will come soon after my last dealership oil change (under body aero).
But I was looking into changing my Mirrors, seeing how I have not found anyone that has done this yet. The factory Mirage power mirrors are likely a bit heavy for a mirror and very large, I am not as hard core as some on ecomodder and would like to still have external mirrors... just smaller.
I found these on ebay.
