Those cars are pretty rare. I think there is only one in my region that hasnt been stolen yet and its owned by an old black lady. But as for the van, Im not entirely sure on what they came with versus the trucks. I know in the trucks the 99.5+ had bigger injectors, different turbo wheel, a few other things. The trannys are pretty good in them so long as you dont put too much power through em. Have fun out there.
