 Based on an Avia 3500L chassis-cab, it featured an air-cooled Deutz engine equipped with German Magirus firefighting equipment.In the early 70s, AISA was taken over by its main competitor Motor Iberica, manufacturer of the Ebro range of commercial vehicles, and gradually Avia vehicles became little more than badge engineered Ebros.All new models were now called AVIA-EBRO.
