As far as a passenger side mirror delete, I was thinking about that, but there is the rare occasion where I do like having that mirror. How much FE would that net me?

Well, I have relied on the ABA testing and other reports made by members of the forum. Search for grille block testing and you'll find some results posted by people. As for FE and the mirror deletes, I remember I think MetroMPG posting about an industry study suggesting 3-6% of total drag on some cars can be attributed to mirrors, which could mean 5-10% of the total mpg rating--seems high to me. If you search for mirror delete and FE or drag, you'll find it.
I recommend giving it some thought. My grille blocks are not optimal because I chose a "stealthy" install and so they are not flush with the outside of the bumper and body, but are sunken into the grille instead. I want the mods to look good too, as much as possible. Also, check your state's laws re: mirrors. I am in California and by my reading, I need two mirrors that can see at a distance in the traditional directions, but the law says nothing about any being outside. But I am not a lawyer, so consider your own take regarding the driver's side mirror in particular.
Oh, I'm in coastal Southern California. Weather is great, but the topography is full of hills.
