And the others anyone?
#3 is a Fiat 1100 and given the location I expect it's a TV.
It is indeed a Fiat 1100, but not a TV because it doesn't have the third headlamp in the middle of the grille. The #4 is another 1100 and actually we don't know wether a TV or not, because neither the grill nor the tail are visible; being in single-color, however, I should say a standard version.
#1 is probably a 1953 Ghia 1100 Siluro Abarth
Yes, that's indeed the Siluro 103 by Ghia.
Only the 5# is still unidentified, but is quite easy...
Only, it is strange to see one in front of Abarth factory.
