I also think about visiting Buenos-Aires this winter and my boss (she is from Argentina) told me that it's very!!! important to take only known cars. Many people there have a phone number of their own taxi driver, sometimes important people, like former Finance minister Caballo, have taxis parking close to the door of their house. But to be cautious is very important in Buenos-Aires. Especially with taxis - be careful not to be robbed or even kidnapped.
