Old cars and traffic rules

Argentina's traffic is civilized and there are no tricks on the road for us Swiss drivers. Well, almost none, as it seems right of way (ROW) and yield are not as strictly handled as elsewhere. It not unlikely that you will get the ROW even though it's clearly signaled that you have to yield. The opposite will be expected from you, too. So, it's just looking out and respecting the other. If he's already rolling and you are slowing down, let him pass – keep the momentum when you have it.
Where there's a big difference is with the age and the state of cars. You'll find the very latest models on Argentina's roads, with a strong tendency for French cars, Volkswagen, Chevrolet and maybe Ford. You'll rarely see a BMW and probably even less often an Audi. No Volvos at all. If you like driving wrecks then Argentina is also your place: Noting like Havana's graceful American cruisers, probably you won't see cars in worse condition even in Bolivia than you do here. Argentinians seem to have no problem at all to drive a car with a wooden rear door or without a fender. In that category of car Ford (Falcon) is very well represented along with Fiat (mainly 500 with crooked wheels, no color, missing lights) and some French Peugeots or Citroëns (even 2CVs).
