The "new" Mini there is the Countryman, it's much larger than the "new" Mini circa 2001...

Point taken, but that might be more akin to comparing a 2013 Porsche Panamera to a 1963 Porsche 911.

With many cars's cross sections getting larger (both wider and taller) over time (+ people getting fatter and fatter), the Cd will be increasingly important as the area "A" continues to rise.

An interesting study in frontal area, time, function, technology and designing for the conditions of the road.

The area's look near equal and with the reputation for race cars being that of high drag, I have to wonder which one is the more aerodynamic.

I'd guess that the antique/vintage racer would have the lower Cd (maybe 0.90 vs 1.2 for the F-1 car),we'd have to compare frontal areas for drag factors.

I did quick study, not real accurate or scientific, but it still looks close to equal to me.

That being the case, then the old timer would probably have the edge.
The 1906 Buick Touring Car was reported by Alex Tremulis to have the highest Cd ever recorded for a passenger car.It had no windshield,allowing ram air to slam it's parachute fabric roof.Tremulis reported around Cd 1.1 for the Buick (if memory serves me).
Since the racing car is roofless,we'd have to discount its drag compared to the Buick,so Cd 0.9 is just a S.W.A.G..
