Car / camper wanted / South America

Wanted: car/van in South-America starting January 2018

Hi there!

My boyfriend and I are planning a road trip through the South-Americas. We are still trying to figure out how purchasing a car and all of that (incl. getting rid of it) works. We would preferably start in Colombia and take it all the way down to Argentina.
Any tips? Would love to hear it.
Any cars or vans or sorts available from January? Let me know and keep us in mind!

Thank you!

Looking for a Camper for 5

Hi All, we are a family of five from Australia,  our 3 kids are doing home schooling for 11 months, so we need a camper for our travels around South America. Currently in Canada waiting to fly down south to get out of this cold! If anyone has any leads or are selling let me know.
Thanks  David
