Weird story. The time to research the value of something is before you sell it. You did a nice thing and the guy was extremely lucky that he sold it to you- there are a lot of people who make a living by finding under-priced oddities and antiques at garage sales and then selling them online or at their antique shop. In fact, the entire antique industry in the U.S.A., (probably the world), involves traveling the back roads of rural America buying stuff for a fraction of its final (big city) value and reselling it. It all comes down to knowing your **** and being ready to jump on something immediately. It's a business where you must have the cash on you, no "I'll be back in 30 minutes/just have to run to the bank" stuff.

If you found someone selling a '58 Speedster out of a barn for $10k, would you educate them as to its real value or jump on it? It's an interesting ethical question. Most knowledgeable Porsche people would not tell the guy holding the pink slip that it's really worth $250k, I'm guessing.

I would not sweat it but the guy did not deserve to get it back, IMO.
