Yeah, many of us norteamericanos on Flyertalk rent a lot of cars so we're good at playing the discount game (and it can be quite a game in the USA). Some of these tricks work, to some extent, in South America (like we can sometimes use our best discount codes to save a few bucks at the big chains). But I don't think anything is going to "work" in Argentina for a multi-week car rental. The price is going to be thousands of dollars, especially on a one-way rental. So I think I'd have to rent the car in Chile and take it across the border. Or not do the road trip.
