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

I did $5500 at a Fall Fling.

Bought out a huge stash of E-body parts from a guy to get a fraction of cool items out of the total.

It was a FULL U-haul box van full of parts. I didn't have a place to store that much stuff. I had stuff laying out in my backyard, in my living room, in a full garage space, etc. And lots of it was tough to ship. At Fall Fling I unloaded the day before. No way I could of setup the morning of.

So I sold E-body dash frames with core pads for $75, A/C dash assemblies $50, Rear seat frames $40. Priced to move. Most buyers flipped that stuff again. Lots of meat left on the bone.

End of day there wasn't much left. most fit in a couple of Costco totes. I sold some good items before the show. I still three times'd my money and I still have NOS Doug Nash 5-speed w/shifter, rebuilt 3.55 SG, and about $2K in E-body parts.
