Argentina has a strong influence from Italy, France, and Germany. I think yall use Ciao for hello, don't you?
I know Astor Piazzola is a badass.
Juan Peron ruled for quite some time. You had a native tank design called the Nehual, Nahual, Nahuel. Something like that...during WWII.
Juan Manuel Fangio, one of the greatest racing drivers of all time, is from your country. He drove a modified 1939 Chevy. You also had a Ford plant for a long time...at one time at least you drove on the opposite side of the road as us Americans. Your cars were RHD.
One of the coolest variations of the AMC/Rambler American was built in your country. It was called the Torino, first assembled by IKA (Industrias Kaiser de Argentina, ironically, another American transplant), then Renault bought that company and continued production. It used a Jeep OHC six cylinder. It was heavily modified from the original Rambler American, which I think is justly reflected in the conception that it is an Argentinian native vehicle. I believe the changes made make that assertion correct. Later on the engine was extensively modified by IKA, including a new block and crank design. Very cool stuff.
That's about all I know.
