IMHO it's a 1946 Cadillac "Series 75" Fleetwood sedan or limousine. These Fleetwood bodies were basically the same from 1946 through 1949. However, because of the chrome-edged running boards, we can eliminate the pre-WW2 Fleerwoods (1941-42); also, because of the six horizontal grille bars (visible in the smaller image) we can eliminate 1947-49. So we are left with 1946.
I got your email Antoine however this Cadillac only appears in 2 shots, one with it driving up the driveway (as shown in the thumbnail), and the second with it entering the courtyard (main image). If you look at the thumbnail there are trees block the view of the driveway, this means you can't get a full view of the car as it passes by. So the main image is the best image for the car. But if you want to reuse this image to make a listing for the Cord Coupe, I have no problem with that, it's not what I consider to be a random background vehicle.
