Why is gas so expensive in Wyoming?

I’ve become a bit of a car enthusiast recently, and have become particularly interested in cars with a high RPM. Do you know some of the highest revving diesel cars?

I have four kids, so driving a minivan just seems like the natural choice. I’m looking for a minivan that doesn’t guzzle down gas, and I’m curious about the Chrysler Pacifica. What kind of gas mileage does the Pacifica get?

What elements do I have to combine to make a car in Little Alchemy 2? I want more cars because they’re important for a lot of other things but I’m not sure about the different ways that I can make them.
