Automotive history presents examples of "high unit sales" being of secondary importance. Of course, no manufacturer is willing to sustainably support a product that is returning nothing other than financial losses. But the "halo" function is not to be dismissed. As a presentation of what is technologically and stylistically possible, a showcase for what can and perhaps will be "trickled down" with the costs of which being diminished by economies of scale, etc. Or maybe simply to place a public magnifying glass on an automobile that has the qualities of becoming an enduring aspirational icon. Especially U.S. manufacturers embraced this decades ago. The FoMoCo's 1956-57 Continental MKII that was produced for less than 2 years and was a loss-maker from the beginning, but remains a legend. The same can be said for the Cadillac Eldorado Broughams and Biarritz of 1957-58. Or Studebaker's 1962 Avanti. These particular automobiles contributed to FoMoCo and GM selling a lot more of their far more pedestrian offerings. Studebaker did eventually go under, though.
I know, this is primarily stuff for automotive historians rather than participants in the "ICE versus BEV" debate. Yet, IMHO, it remains a valid case in point.
