What is the best/worst you've done when selling at a swap meet?

Walking around the Nats swap meet a few years ago and I see a 67 Barracuda hood leaning against the fence in someone’s spot. Super clean hood, and the inserts were perfect. I ask him how much and he says he’s been asking $200 all day but everyone just wants him to take the inserts out, give them a super good deal, and leave him with just the hood. He tells me $125 and get it out of his spot, he’s done with this ****. I get out my money and take the hood and all. Took it back to my truck and was followed by at least 3 guys trying to buy the inserts from me. I removed the inserts, put them in my truck for safe keeping, and put the hood in the bed. Still have the inserts in Nellas car, and I gave the hood to my buddy for his Formula S car that was in a fender bender. Best $125 I’ve spent in a long time. Yes, the inserts are still perfect, they even have the light argent paint still on them and looking good! And not a pit on them.
Nice. What are a pair of those inserts worth in that kind of condition?
