Captian Obvious Driving a cool 65 Formula S??
Think I've figured it out!
One of the reprint catalogs I have is the "1964 - 1969 Plymouth Barracuda Information Manual". In there, it shows a side view of a black '67 'Cuda Fastback (one of three body styles offered), which seems to be a dead ringer for the ObviousMobile--right down to the styling of the wheels.
On these second-generation 'Cudas, the fishbowl was smaller and shorter; however, the C-pillar profile looks very similar to the earlier cars and the interior lights on these pillars have the same distinctive round shape.
At the risk of stating the obvious: Something is "obvious" only if you recognize it, which means you must have seen it before...
