It does require a leap of faith since asking for references is out of the question.

I spent 25K one time on a ZR-1 in Alabama site unseen. I have owned it for 10 years !
This is where the power of the ORG or some other site you have made friends on can come in handy. Simply recruit some other like minded enthusiat that is willing to help you make the transaction.
Example. The Busa you want to buy is in my area. You ask me to look at it, inspect it, and make sure the numbers match. Once satisfied everything is in order I call you and let you talk to
the seller one last time to confirm everything is as it should be. Then I physically handle the exchange of paperwork and cashiers check if your not wiring the money to the seller.
Then the shipping preperations begin in whatever arrangement is decided upon.
So, where is it ?
