Selling bike with Power of Attorney
 

Hello!
I'm nearing the end of my trip and want to sell the bike in either Bolivia or Peru. I bought it from a Brazilian, who in turn bought it from the original owner, an Australian. I have a chain of Power of Attorneys, and it has worked perfectly the past 2 months, 2 borders and numerous police checkpoints.

So my question is: if I want to sell it, I meet with the buyer, we go to the notary together to make a POA in the same style I have, I exit the country with him as pillion so I don't have the Aduana stamp anymore, and he enters the new country with me as pillion. Is this correct? I might be completely mistaken but I think I read this here somewhere.

I know this question has been asked numerous times, but Fast Bolivian Internet is a contradiction in terms and searching would take years.

Thanks for the help!
