Here's the section when they tested a MB wagon:

....

The hatch window of the MB is even more slanted than my 9-5, and it doesn't do squat for aero, it seems. There is one term, though, that I'm unfamiliar with; what is meant by "suction peak?"
What I noticed was the big effect the side view mirrors have :

That looks like a big justification for a side-view mirror downsize/delete.

Yes but they also widen the forebody there to a certain extent and possibly allow flow to come in at more of an angle behind. Also have to be careful messing with mirrors in that a smaller mirror with a fully blended root, can in fact cause more drag than a larger mirror out on a bit of a neck. That was something that turned up in the '08 Caravan redesign, think it's mentioned on the allpar site.

Thanks. I am in the middle of downsizing, and I will be using this :

This might have the "root" problem you are talking about. What is good is that it should be easy to tuff-test. I will keep my passenger side mirror stock and compare the two. If it fails, then I can swap it out with other (flush half-conical?!?!?!) mirrors and test accordingly.
