i have been selling there for the last 20+ years.
we sell mostly scratch and dent VW Mazda parts.
don't have many Mopar parts left to sell.

just a hint THE EVENT IS BIG. there are something like 5,000 swap spaces. it will take you days to walk all of the swap. the best part is they check the swap spaces for car related parts for sale only so there won't be to much worthless junk for sale. unfortunately with the seller counts getting smaller more crap is starting to pop up now.
i am not sure on the amount of cars. something like 2,500 show cars of all makes and 1,000 cars for sale.

THE EVENT IS WELL RUN. the garbage cans almost never overflow. the bathrooms are clean and maintained. the food is reasonably good. the pancake breakfast is great.
you won't have a bad experience other than spending a lot of $$$..
