Foriegner Buying a vehicle in Argentina?
 

I am an Australian trying sell a motorbike(registered in Peru) and buy a Van. I don't mind where van is registered but cant seem to find any where with international car sales anyway. Im even having trouble finding anything second hand. Im fairly inept in Spanish aswell, which isn't helping
I read some old threds saying you can get two names on a register (green card) 1 Me, @ an Argentine resident. Then get them to cross the first boarder and hand the car over to me. Is it only the exiting of Argentina that is the problem?
I want everything completely legal so I don't run into any problems.
I didn't have any problems boarder crossing with the Peruvian bike I just need more space.
Any info would be great.
Thanks
