With lack of instrumentation it is really hard for me to tell if there are any positive effects from the mods I am doing. I think the passenger mirror delete helped as that tank I got 46mpg, the following tank was only 40mpg but I had a lot of not normal driving for the first 100 miles.

Before I took off the passenger mirror I bought a panoramic rear view mirror and I have to praise that little gem, I can see 2 lanes over and have no blind spot at all on the passenger side...it does take a little getting used to, but it surely helps visibility. Even if put the passenger mirror back on, I will still be keeping the panoramic one...
It's hard to predict the difference it will make.
When GM was doing it's Precept PNGV car they had budgeted 30-counts for all the features drag on the car,which would include the mirrors.
If you took the entire 30 counts off the Saturn it might be tough to see it at the gas pump.We know the drag would be reduced,but it would be really tough to see it through the signal-to-noise ratio of road testing.
Just shooting from the hip I'd say,remove them and you'll see lower drag.Whether or not glass is up or down.
I'm keeping mine for safety reasons.
People around here get their drivers license from a box of Cracker Jacks.You never know what they're likely to do.If they put me in a pickle ( a daily occurrence commuting to jobs) I want to know exactly what my immediate environment for maneuvering is.
