The owner of Zoo Lujan has collected a variety of older vehicles, especially trucks like this one. While the privately owned zoo itself is a bit controversial at times, there's nothing really controversial about these trucks.
The zoo is a good 45mins-1hr outside of Buenos Aires city. I visited as a day trip to see and play with the animals, although with it being a hot day out, a full day was a bit long.
