If they want to buy it back its not for sale but hope to find info on the company.
I understand that you may have put a lot into this truck to make it your own. But I would hope you wouldn't dismiss out of hand the desire of someone to have what was their original vehicle back. Sometimes it helps, in these type of situations, to imagine the shoe on the other foot. Suppose the truck had been your father's, and after 50 years of loving care had to give it up due to financial reasons from a health issue. Now, 30 years later, you have the resources and would dearly love to have the old girl back in the family (imagine - you were able to locate the very truck your dad owned, and you used to ride around in!). But the current owner won't even consider selling it.
