Good to know, Thai. It is pretty hard to beat a minivan when it comes to carrying people that the things that go along. Ditto on the calculations. That knowledge makes it hard to spend extra money for something like a Prius anyway, but I honestly think that the Prius is a much nicer car than an equivalently equipped Corolla/Matrix. Paying the "hybrid premium" helps shield you from gas prices a bit more, they are super reliable, they have low maintenance costs, and you should have better resale value. All in all, I think a Prius is a pretty darn good buy all things considered... not just looking at gas mileage.
