Are you looking for a Ford Transit cargo van or just a cargo van in general? A lot depends on if it is a T-150, 250, or 350 and which height you are looking for. Some have run through the auto auctions here in Texas for $22,000 to $25,000 with close to 20,000 miles on them. Prices will get lower when the first group of fleet vehicles start showing up, usually when they get past their lease term.
Where are you located and what specific cargo van are you looking for?
