I had posted these pics in an older thread about this car. It was on display at the 1974 Chicago Auto Show.

The black car on the left is that a 74 SE Trans Am ? I thought they were released in 76 .Or was this a prototype show car as well ? Or just a black Trans Am

That's the Bill Mitchell 1973 Trans Am 455. The car was painted black and gold, then had an SD-455 installed. Pontiac updated it to the new 1974 nose and tail and sent it out on the auto show circuit. In 1976, the same car was updated again with a 1976 nose and tail, and they cut the rear window for the wraparound glass. The 1976 version of this car would be the one they used as a model for what would become the 1976 Trans Am Special Edition.

Anybody notice one picture has no sunroof visible and the auto show picture has one (glass, not steel). Late add before the show?

some of the design study cars don't even have internals in the engine or trans to save money & time. Some don't even have brakes on the car so the cars or cars aren't safe. I've seen at some shows a long time ago , in the early 70's with no wiring.

After I looked again, it might be open rather than glass.

That is true.

This one is actually a fiberglass buck on a tube steel armature.

To me the picture in Post #6 seems to have an open sunroof. ( I could be wrong) as for the other shots I would bet they were airbrushed out for some reason. The car seems to have the standard retractable sun roof to me.
