Trotting out this old horse again? There is no such thing. Any licensed dealer that sells a firearm to anyone at a gun show must run the standard background check. That makes it absolutely no different than purchasing the firearm in a regular store. No different whatsoever. Even if any part of the transaction is initiated or conducted at the gun show, the background check must be run. So there is no "lets meet in the parking lot and I'll sell this to you." It just does not happen, period.
What can happen at a gun show - and what can happen anywhere - is a private sale. A private citizen (ie. not a licensed firearms dealer) can sell a firearm without a background check. That's a private transaction, period.

I’m in Washington State and I signed up as a “member” of the “gun club” so I could go to a show and perhaps buy a gun. They run the background check on you when you join as a member, so the seller at the show doesn’t have to do it. I believe that only members (with the check) could buy guns regardless if it was a private sale or a business. But with the private no record of the sale, while with the business need to run the sale through the database with the serial numbers, etc. And I’m pretty sure no waiting period on handguns either.
Signs at the door warn that it is illegal to buy or sell weapons in the parking lot, etc.
