'Offered a lot of money.'
Sounds like a deal too good to be true?
So then it probably is.
Belarus made a lot of tractors, and frankly they are not so well thought of for quality.
Why would anyone offer more than you are asking for a product that needs a lot of shipping, lot of export issues, for a product that is not rare nor especially good?
Why would any of that make sense, when we know there are thousands of scammers out there?
