For 1940, The Packard 160 and 180 had vacuum wipers and radiator shutters.
Another fact I find very interesting: In 1940 Packard had the 110,120,160 and 180. The sedans of all series used the same body shell. The coupes of all series used the same body shell.
In 1940 Cadillac/Lasalle had the series 50, 52, 62, 60, 72, 75, and 90. The sedans of all series used 5 different body shells. Same for coupes. 52 and 62 shared one, and 75 and 90 shared one. 50, 52, and 62 shared bodies with other GM divisions, which is why Cadillac/Lasalle was able to field 5 and Packard had one.
