The Laws of Physics tell me it must have been a mega impact on the glass (window ?) to travel far enough to cross the sidewalk & hit more than one car. I'm curious.
If you see a lawyer, your first 'contact' appointment should be free (well, if the lawyer is not late...

) but nevertheless, how bad is the damage on the cars ?
If the damage is your mistake, then indeed I recommend you settle things (karma is quick to catch up) but a lawyer for this kind of case will charge you a minimum of 1200/1500 pesos I guess.
If you want to hire one because you don't want to pay anything (your business) & if you don't own any property here (no car, no real estate, nada) = then don't hire one (you own nothing here, end of the story).
If you want to hire one because you're ok to pay but just what's due & you're scared : if you own nothing here you don't have to be scared and can sleep better tonight, and in this case better not hire a lawyer. Put yourself in the shoes of the claimants then (they know you own nothing here & they likely are Argentineans so the first question they will wonder, being Argentinean, is "does this guy owns anything here ?"). Then negotiate fairly & ethically.
If you own property here, better see a lawyer indeed.
Anyway, you can also take advantage of the fact lawyers don't charge the first consultation and see five of them freely...
