Correct me if I am wrong, but do any of the Jurrassic Park movies have a VX in there?

I was at a gas station last weekend and some dude comes up to me and was like, "You must like Jurassic Park!"

I was like, "Huh?"

And then he said, "You know, Jurrassic Park, where they had all these trucks like yours, I haven't seen one of those since I watched the movie."

And then I said, "ummm, ok" and got in and drove off.

I am pretty sure those were Land Rovers or something in Jurrassic Park...I've only seen the movie once, so I can't really remember, but I definitely do not think there were any VXes in the first movie. What about the sequels?
