At the pace you've been going I wouldn't be surprised. [perhaps I'm thinking about the wind tunnel thread] Maybe it's down to filling in the details. From the link that was hiding under the color picture:
Quote:
Johnson had his own chassis enclosed in the first body by August of 1959, when it was possible to run an airflow observation test at the Riverside International Raceway. White wool tufts for determining air-flow direction were easily visible against the dark grey primer, and sections that had already been cut out of the body for the two headlight tunnel openings were carefully taped back into place to provide a completely smooth form.
Howard Miereanu (now a General Motors designer, but then a student at the Art Center School in Los Angeles), possessor of a Bolex 16-mm motion picture camera, was perched in the passenger seat of an accompanying car and panned past the coupe which was run at steady speeds of 60, 70, 80, 90, and 100 mph down the 5,100-ft back straight of the race course. Viewing this film at slow speed later confirmed theories that some of the top boundary layer could be diverted around the corners of the cab by use of a sharply peaked cowl and windshield, and that the general air flow was true to the developed contours with a minimum of turbulence.

There were two or more cars built on different chassis from the mold that followed a series of articles in Road & Track.

So how many of Mac’s LeMans Coupes survive?
That’s a great question! The one in California is no doubt still out there. I found another on Ebay. A third “body only” surfaced in California, and a fourth one was found in Minnesota. And more may be rearing their heads soon.

Here is the van's story, minus the batman treatment.
The Amazing Maltese Bread Van
I do like that tow truck and 1922, Florida (Pablo Beach) racer.

plan-taper and separation

In the Schl'o'rwagen you'll notice in plan-view,that the body taper begins right at the front wheels.This is what we'd be looking for.
Here is the 'ideal' section contour,center image:
PS,we'd have quite a bit of design latitude with the nose,but the tail would want to be dead on.Volkswagen's Rolf Buchheim pulled off Cd 0.14 with his long-tail 'Flow' body in 1981,using small,'optimized' radii on the leading edges.

Electric cars | Hemmings Daily

* The Petrol Stop has been on a roll lately, finding intriguing cars to profile. This week it was the Weidner Condor, a fiberglass sports coupe designed by the same guy who designed the Amphicar. The Lane Motor Museum has one, pictured above. - See more at: Electric cars | Hemmings Daily

Weidner Condor S70
The Petrol Stop: Weidner Condor S70
Quote:
First off no this is not a renamed Porsche 356, it may look similar but this was advanced in a few areas away from the Porsche. Designed by the guy behind the Amphicar, so this was a bit of a departure and it was built by farm equipment manufacturers Fritz and Reinhold Weidner. Utilising the most modern and expensive of automotive materials at the time, namely fibreglass made it unique in 1957.
It has a three cylinder, 662cc, two-stroke, water cooled Heinkel engine producing 32bhp. Enough to get it up to 80mph. Unfortunately it was up against the gorgeous Karmann Ghia, and due to its "state of the art" body meant it was very expensive. Much more than the Karmann. Still around 200 bodies were produced between 1957-58, its unclear how many cars were actually constructed though.

Point taken. I'd left off the " "
Weidner Condor S70
Now that's nice, but I was reminded more of the Marquis than Porsche, what with the fiberglass body and all:
