Hi
Does anyone have experiences that can help with specifics of transferring ownership of a uk registered vehicle whilst it is in South America?

We have British friends, travelling in a uk registered 4x4 in South America
When they return to the uk for 9 months later in the year, we plan to fly out and have an adventure in that 4x4 (we are also British).

In order to deal with officials and borders, we'll need to have the car ownership in our name (is anyone travelling in a vehicle that isn't?)

To do that i assume we will need to do the following, any comments?

- join our friends when they cross the last border before the handover
- they deal with paperwork for the country we're leaving, and ending the Temp Import Permit (TIP) there
- we then all sign the "Sales bit" of V5
- we then hope the officials at the country we are entering will put the new TIP into our name (new owners), and continue. (I've not met many border officials who wouldn't make that difficult or potentially costly or impossible)

OR maybe...

- Wait until our friends enter the last country they intend to visit before the handover, and get them to send us (in the UK) the signed "sales bit" of the V5, so we can sign it and get the ownership switched in the uk
- We fly out with the new V5 in our name, and join our friends when they cross the next border
- They deal with the vehicle leaving the first country, and ending the Temp Import Permit there, using the bit of the V5 they have (or a copy of the old one with there name on it). (Here lie potential issues again!)
- We deal with entry to the next country, getting the new TIP in our name using the new V5

What have other people done?
Any thoughts on weather Peru / Bolivia or Brazil are better options for this?
Any info great fully received!
Cheers
