Check out the car on the cover of the South Carolina 2022-2023 Travel Guide found at the Welcome Centers on I-95. Bet Jason Edge can identify the make, model, year, and maybe the owner.. :) :) :) :) SC Travel Guide 2022 1.jpg
Squared seat pattern is more like the 1963 Series 62 Convertible than the elongated diamond pattern of the 1964 de Ville convertible ... but there should be a smooth bolster section at the top of front and back seat and I see a seam running to top on front and back seat. Definitely not Eldo, my vote is 63-6267 with redone interior with seams to the top. Not sure whose car it is?
They've been using that in recent TV ads too down here(SC). I don't know if that's for a series or just ads. I didn't study the car but recall seeing it and that guy.
