i did search for this in solved section but i do not know why it wasn't there
as I know this was Ghia proposal from 1962 both sedan and station wagon for new model range for FSO Warszawa
there was driveable prototypes but due political order those was scrapped, unfortunetly
should I give a point for a repost puzzle?
Actually I think the 1959 date is far more likely.
Ghia would never have come up with such an out-dated proposal as late as 1962, e.g. the suggested fins at the rear; the headlights on top of the front wings. By 1962 bodywork was much smoother and flatter and the headlights would have been incorporated into the grille as was pretty much the norm already in 1962. Compare it with other Ghia designs from 1962!
In my defence I didn't know it was a repost until after I had already solved it; it was only whilst looking for the date that I was offered a picture of the car: on AutoPuzzles!
