I have it as ordered in 1958 and shipped to Poland in 1959.
I quote to add to the interesting, but unfortunate, history of this car.
"Ordered by FSO in 1958 as an update of the GAZ M20-based Warszawa "hunchback", Sergio Sartorelli designed two bodystyles - sedan and kombi (or rather berlina and giardiniera). In 1959 the cars were shipped to Poland but Polish First Secretary Gomułka wasn't keen on such a big, capitalist-looking car being produced in a communist country and they were mothballed in an FSO warehouse and in 1976 destroyed, together with many other FSO concept cars. No photos were published at the time and for the last 54 years no-one knew exactly how the Ghia-designed Warszawa looked. Fnally, after a long investigation, some photos of the cars were recently found in the Ford Motor Co. Archives in the US. Here are three of them (plus one of a scale model)."
