I know a guy who took a Harley all the way down. He bypassed Columbia as well.
Don't travel at night and it is a good idea to travel with a caravan of other vehicles in remote areas. A bus caravan is the best usually, busses are usually not targeted as much because they are so difficult to stop. Remember, a Land Cruiser will automatically make you a target. Plan your gas stops well, not as many pumps along the way, and most don't take credit cards.
Brazil and Argentina have beautiful untouched land. Check out the Iguacu Falls if you get that far down, they make Niagra look like a leaky faucet.
