Marshall,
I think a forum dedicated to selling car stuff ( misc cool items) would be sufficient. that way not only the dedicated few can sell car related items but also it would bring more people to participate in the forums. The picture upload idea is also awesome. Plus its a bit easier to quickly post things up for sale in the forums than having to go thru the main page.
again i give myself out there to help out administrating that venue if the help is needed
p.s. Twisted..lol i know the pump was worth a few bucks but didnt realize how much of a collector item it is. my uncle gave me that pump when i was 15. it was at one time restored. its been in the backyard wrapped up in plastic and tarp for a few years now. if i remember correctly one of his friends that race in the salt flats traded it to him for a 32 ford body. ill dig it out this weekend. lol..its a family heirloom so i dont know if i want to sell it yet
