Hey Gang,
I'm going through the Vehicles rules with ye olde fine tooth comb because I'm running a "super agent" game.
I ran across the following:
5ER, pg. 472
"The vehicles Size and other modifiers affect its DCV, but it can never fall below 0 DCV."
I'd highlighted this in my copy some time ago, but clearly I'd forgotten it. It strikes me that this has some amusing implications. Your crappy old panel truck and an aircraft carrier could both end up having a DCV of 0.
