ElQueso said:The other thing is, that it's unlikely you will get stopped. I have never been stopped in Buenos Aires. At times they set up checkpoints where they will occasionally pull over a car, but the police here are not allowed to come up to you in their car and pull you over to issue a traffic citation. it's unlikely you would ever interact with a cop and a car unless it is related to parking!
HOWEVER. Be careful to get permission (probably a "power", but i'm not sure) from your daughter that gives you permission to drive the car. If for some reaosn you did get stopped, you might have some problems with the fact that the car is not a rental car and you are not the person on the cedula verde.
I don't agree with this. I have been stopped only once in Capital (I must admit I was driving and on the phone ), but as soon as you leave the city there are many check ups. I have been stopped a lot! I never drive without DL or Pasport as the chances of getting pulled over are high. They look at all our papers. They don't know what an international drivers licens looks like. Mostly they ask me where the number is. They always ask the cedula verde /permission to drive the car. Just a note signed by your daughterwill be fine.
