Good catch Art. I was waitingto see if anyone else knew the facts. I love the mystery that surrounds this car.
I've seen a real wartime ZIL--the one that Stalin gifted to Mao ZeDung in 1949. Chairman Mao gave it to his commanding general of the Chinese invasion of Korea, where it was ultimately captured by the US Army.
Truthfully, other than looks, there is no comparison whatsoever between a real Packard and that ZIL: Where the Packard 180's had a level of fit, finish and trim rivaling that of Rolls Royce, the ZIL looked like it'd been hammered out with 9 lb hammers--very crudely finished. IIRC, the ZIL had a huge 6-cylinder engine, where Packard's senior cars were a mix of straight 8's and V12's.
