I am the owner of one of the few renaining examples of FIAT 800 Coupe Vignale, which is in process of restoration. This model had not an equivalent in the Italian FIAT catalog because tha argentina branch of the company purchased the design directly to Vignale. Obviously the base was the ubicuous FIAT 600, but the 800 was notably heavier becase of the great amount of lead used in the body.
