Here is a picture from an unnamed source that also reflects the rear window treatment. It is a Lancia Aprilia 1500 Monviso (what ever that is).

The Studebaker is certainly a styling all of its own as was the bullet nose. Ala Tucker maybe? One begats another. The GTV has several cars in its design.
Anyone have a Savio logo? Maybe it was CarrozerriaSavio on the side of our mystery car?
The people in this thread just amaze me at the depth of your knowledge.
