In 1991, Austria decommished the tank and offered it to Schwarzenegger for free - as long as he paid for shipping. Schwarzenegger was happy to drop $20,000 in order to ship the 50 ton tank because in 1965 he spent a year driving that exact tank in the Austrian military. He said, "That's exactly the same tank with the 331 number on it. M-47. It's exactly the tank."
So what does Schwarzenegger use his massive tank for? He said, "I bring kids out here from the after-school programs. When they stay in school, their reward is to come out here and to drive tanks with me."
Leno and Schwarzenegger took the tank for a ride and even crushed a stretch limo. It looked like the two Hollywood legends had a pretty good time.
