Great thread !
1957 Chevrolet. There seems to be another 600 hidden behind the Lancia.Raganelli hotel: Lancia Aurelia, Mercedes fintail, Giulia, Fiat 1500, Citorën Ami 6, something USA, maybe 2* Fiat 600, and the last Giulia.
Yes. Colli made limousines or "ministeriales" out of 1900s and Giuliettas and station wagons or "promiscua" from Giulias and 1750s. I think I saw photos of an elongated Giulia as well.But what is the 3 windows berline on the left? (elongated 1900 berlina,)
