Mine is known as "Ben"
I was at the Roadshop one day, and a hispanic gentleman walked in. He somehow found the English words to tell the salesman what he wanted. In order to figure out what wiring harness and dash kit he needed, the salesman asked what kind of car he drove.
"I drive a ben."
"A what"
"A ben"
"Uhhhh, just.... pull it around back and we'll take a look at it."
... so he pulls around and he's driving a early 90's chrysler van. So once I got my van, everyone at the shop started referring to my van as "Ben", so it stuck. The only other nickname for it is MAV, for Mormon Assault Vehicle.
