It most likely is a concept car, unless it's something that someone cobbled together over here. Does it look like one of these: http://perso.wanadoo.fr/thierry.roustit/expo43/chryghia.htm

That's all I could find under "Chrysler Ghia" and "Dodge Ghia".
Thanks for looking around! But no, neither, not even close unfortunately.
This one looks very italian 1966; clean lines, hood slopes down to thr ground in front, tail slopes down. Clean, thin, low, horizontal grille. That first one's (above) grille is about 2-times too tall, and has that 50's prominence (mouth full of braces).
This thing is spare and clean and smooth, Porsche 911 style, very approximately, but lean, not muscle-fat-ass like the 911. Big greenhouse, relatively. Low beltline (I wish I could section a Hornet 2").
