Excuse my lack of Spanish, my name is Albert, I'm 29, and I will be arriving in Buenos Aires on February 1st. I realize that this is after the time window proposed by you, but sharing a car within a group and exploring the country is just exactly what I would be looking for. Maybe we could work out an arrangement between ourselves and together with a few others?
I'd be delighted to hear from you,
saludos de Viena/Austria,
