Volkswagen Vanagon Forum : “Dose any one know were I can find a 1975 Volkswagen van for sale CHEAP under $1...”

Try Ebay.

EBay is OK, but to get a bus from an enthusiast I'd go to www.thesamba.com  In addition to having a great
classifieds section they have information and links to just about everything you need to know about aircooled vee
dubs.  Another EXCELLENT baywindow bus resource is www.ratwell.com  I'd read his "how to buy a bus" article
before buying anything.  Check it out!

You can get them in the places listed above. But if you only spend $1000 be ready to spend triple that to get it on the road. The saying is true that you get what you pay for.
