When I bought my 150 it had to be flown up from Melbourne, to where I keep it in Sydney - overall it was only about a 5hr flight, though done over two days due weather. I didn't have the spare time and the seller had a friend who wanted to do the ferry flight (which I paid for the return commercial flight)so it was delivered with him working out the logistics as such. As it happened, the guy was happy to pay the fuel bill for the experience which was a nice bonus too.
What did happen was that I paid for the aircraft before it left Melbourne, however the official paperwork for transfer was not completed till arrival. The seller kept it on his insurance until delivered as part of the deal.
So all in all, it worked out well for everyone concerned
Cheers
