click the link I posted above with label "home movies" - there's a white 73ish satellite in the first few seconds. If an actual later coronet, probably part of the test fleet the EPA had. There's a clip of that one out there somewhere too. Part of the 1980 loan guarantee package was scraping the turbine program.

just looked again and I swear there's a Cordoba in the bay next to the Satellite. Around 20 sec in there's shot of a door with "Department of Energy" on it. Makes more sense than the EPA. also: who else but Chrysler engineers would swap a motor while wearing a shirt and tie?
