Ship or buy
 

I am from Europe(Sweden)
I plan for driving in South America for 3-6 month

Alternative 1:
Ship my bike to Chile (or Argentina)
But I heard Chile customs are better


Alternative 2:
Buy a bike in South America.


What is the preferred alternative ?
Mainly looking at cost.
Shipping round trip.
Or cost of buying-selling bike?


For Alt 1: Any recommended carrier company (boat)
For Alt 2: What title should one require for the bike. I have seen bikes with US, European, Bolivian, Chile papers.
What is legal ? What can be insured? What makes boarder crossing possible without problem= duration of stay ....
