I own this car since new.
This is NOT a 1300 Giulia.
This is an Alfa Romeo 2600 concept car and only one was made for exhibit purposes in the São Paulo Automobile Show of 1972, but was never shown because the factory closed its doors and everything was dismantled or sold in auctions.
My father bought it in one of these auctions, that were not public, but opened only to selected people because this factory belonged to the national government.
This car was made in Italy in 1972 ordered to Ghia by Fabrica Nacional de Motores of Brazil, that made here the Alfa Romeo Berlina 2000 under license of Alfa Romeo of Italy.
The base platform that this car was made is from the Alfa Romeo Berlina 2000, although completely modified and using an added chassis.
The engine is a modified and enlarged 6 cilinder from the 2600 , as well the gearbox, disc brakes, etc.
