What Would you do

I once sold a 70 340 dart to guy that had been asking me to sell it for years. This guy had a 69 GTS and a 72 Demon and had wanted my 70 340 Swinger. I really felt bad about selling it...like I made a big mistake. After waiting a few months and debating what I should do, I went to his house, talked to him, and told him the truth. He admitted that he didn't drive the car as much as he should and agreed to sell it back to me at the same price I sold it to him. So my advise is go talk to him...you never know what might happen.
