Visit the websites for the different builders. You can check out their websites by clicking on the link below. Email with one of their reps to see what it would take to import a car into Italy, there may be some restrictions. I don't personally know of any Spyder builders in your region so I can't help you there.

Used Spyders sell anywhere from $30,000 - $55,000 US with new ones probably starting at about $45,000 - $55,000 depending on engine choices etc.
