I know a guy who dose this all the time for his uncle in a south American Island.
He said down there a car with 50,000 miles is like one here with 200,000 miles. See they are on an island. And I guess many cars that end up there are stolen from here. Heh, anyway. Since they are on an island if a car has 50,000 miles on it they assue it has been driven the hell out of.
I know it can be done, but not sure exactly how. I will see if I can find him and mabey reply to you in a P/M probably will not though since it is illeagle and I do not know who you are. Yea actually I won't put myself in any risk like that.
Sorry man can't help you.
