Well I've never seen one of these before! This custom 1964 use (which we presume started life as a Daytona of some sort but that's just a giess) was advertised on Favebook marketplace in September 2022 asking $18,500. The car has been significantly modified into a pickup, and looks a little awkward at the rear (might be corrected by improving the rear cover.. I do think they've done a good job with fitting the C-pillar / rear screen, giving it that El Camino look.
