Tank II - Tank was my '86 Chevy fullsize van. Tank II isn't as large, but still has managed to come out better than the other vehicle in the collision - just like Tank did.

I usually call mine "My Mortage Payment" cuz the payment is almost as much as my house payment is. Also bean referred to as "The Bitch" or "The Beast".
