1955 Cadillac Eldorado Picture, Classic Car Pictures

But those headlights and the main body line ('hip line from headlight to tail light) slightly curved stance are look very Fiat to me. Like so:

So, given that these are concepts like you said I'm going to say it's one of two:

1. A Fiat Spyder concept in collaboration with Cadillac?

OR (and #2 is FAR more likely as the Italians were way ahead in design and curved body panel manufacturing technology back in the day):

2. A Cadillac concept built in collaboration with Fiat?

Damn you and these super difficult cars to figure out!!! :
