The Wikileaks Truck has no official connection with Wikileaks, but it does have some radical cred on account of it having been confiscated by NYPD and temporarily "lost," then recovered during a stint at Occupy Wall Street in November. It runs, fitfully. As far as Wikileaks souvenirs go, it's way better than the bag of coffee signed by Julian Assange sold during an official fundraiser.
The truck has nearly 200,000 miles and bidding starts at $7,500. Makes an excellent birthday present for someone you want to be sure is under government surveillance at all times.
