I bougth to my touareg Opel corsa mirrors, which were really cheap about 30 per piece online.
I am hoping to see a 0,015 drag drop in my touareg which has huge mirrors at the moment.
One motivator I believe to door mounting is reducing the aeroacoustic noise. Here's a video on the Ford Mustang where they discuss just that:

The aerodynamicist in the video implicate the purpose of moving the mirror to the door is to limit the interaction between the vortex coming off of the mirror and the side window. You'd have to think there are drag (reduction) implications there too?
