Did I get this right – You have actually sent a MC from the UK to Buenos Aires by air for £850 total? If so, then that was quite cheap. Maybe this is no longer possible.

But I also remember back in 2008, when I was looking to send my bike back to Europe from Oz by sea, I got quotes from many companies, and the one that I chose, offered its services at about 50% of the price of the next cheapest company (and the others were not far from each other). First I thought, that it can´t be right, but then luckily I heard of a few others, who had used this very same company, and with positive experiences, so I decided to go for it. Glad I did, as I payed roughly 500 euros at the Australian end, and about 180 to pick up at the port in Helsinki (although that latter one did feel a bit ridiculous, compared to what the ocean freight from another side of the planet had cost me – sort of Welcome to the EU, I guess!!)

Of course I do not know, what they would charge me now. Just meant to say, that the prices can (or at least they could!) vary - a lot - and it seemed extremely critical to be able to find the right guys to do business with. If I had not been lucky enough to get in contact with this one particular company, then it looks very likely, that I would have payed nearly double. Why they were so much cheaper than everyone else that I found, I have simply no idea. Just pointing out, that it could be worth it to still keep searching for a better offer.

....But if you really do have the possibility to fly into the US, and buy there and go, then I´d seriously consider doing exactly that, as looking from the EU, bikes are almost ridiculously cheap over there!
