@Antholin:
This just makes me want my own tank all the more. I know it’s not fuel efficient, but what a sweet ride it would be. Plus, there’s parking everywhere, you just have to roll over a few mini vans.
This is one of the military equipment brokers that I am aware of.

You might also wish to contact either the Polish or the Czech government regarding disposal of surplus vehicles. At the time of the breakup of the USSR, a T-55 could be purchased for about $5,000 plus shipping to the US. APCs were slightly more expensive if amphibious.
