Wow. A lot there and more than I can digest. Let me redirect and try and be clearer on a narrower point. You had written that with a "proper fastback roof contour, the effective static pressure acting over the rear of the greenhouse is at the highest pressure of all roof profiles." I think Figure 7 in the article I linked supports that claim: at the rear of the roof, just ahead of the backlight, the coefficient of pressure is greater on the fastback than on the notchback. Nonetheless, the same article shows that the fastback produces a little more body lift (Fig. 5). For this specific comparison, both your claim and Julian's appear to be true. Isn't that right?

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
