1997 chevy minivan. YES I wanted a bus very bad. I wanted something longer, but this bus ran so good, I couldn't pass it up. It is a 7.8 liter I think. And you are right about it lacking power, but it runs so good. We got it from the Seattle Waldorf School and the owner before them was a school, so they kept it in immaculate condition. I have begun conversion by putting a solar panel on it and 4 deep cell batteries and a solar controller, but I still need an inverter. I do plan on converting it to veggie oil in the near future.

Only reason I say that is because they were generally the cheapest buses they had up here...especially on a Ford chassis. I guess the drivers didn't much care for them. Of course mine is in FANTASTIC shape for it's age and locale whereas the Bluebirds they all liked have rusted away long ago.
