And I don't think a flex-fuel engine improves your mileage, it just lets you run on a mix of gas and alcohol. In fact, I'm pretty sure you get less miles out of E85 than you do out of straight gasoline. Natural gas burns pretty cleanly, but do you live somewhere where you can get it easily? Can you even buy a truck that runs on natural gas? I thought that they only sold them as fleet vehicles.

In short, get a sensible car and save lots of money in the process.

Now, if you can find a diesel truck, you have a couple of options. You can run it on used veggie oil (cheap or free if you can get it straight from a restaurant, but you need to know what you're looking for to get good grease), but you'll need a conversion first; or you can run it on biodiesel. Biodiesel is pretty expensive and can be hard to find, unless you get a reactor and make your own (it can be done, but you can't be an idiot). Also, it's been quite a while since anything smaller than a 250/2500 type truck was sold in this country with a diesel engine, so you aren't going to get good mileage out of it. It's not as hard to find old Mercedes or VW diesel cars.
A local shop near my neighborhood is selling converted natural gas trucks for ridiculous prices, but it's only 89 cents a gallon. That sounds fantastic, but four months ago natural gas was only 29 cents a gallon, so I am a little leery about getting a natural gas vehicle.
