Re: Wow.. I need some advise here...
I would recommend a good firm of Italian lawyers that I have used in the past for a similar problem in Italy to transfer title to France for an Italian registered boat. Try Giambrone Law, my lawyer was Senora Valentina Giarrusso and a link to her personal profile is on their website. They have a US phone number in NYC but she is based in Italy so bear in mind the time difference.
This wasnt cheap but A lot less than €3000 that you email suggests. You will need the lawyers to complete the legal paperwork by power of attorney and usually they deal with the vendor's side to make sure that you get proper title.
i hope this helps!
