Just to clarify I don't actually spend $300 to fill my van but it is over $200 if I fill up at home (Canada). A few months back I started going down to the USA every week to fill up and am only spending about $140 or less. I would love to drive something smaller and more fuel efficient but its just not possible. Since our kids are practically all the same size (2@49lbs, 3@26lbs) they all need to be in car seats. You can not fit 3 car seats across the back of a minivan. We also have a German shepherd who goes absolutely everywhere with us and the need for extra space for strollers, bikes, groceries, etc. So this is my ride, nothing fancy but new-ish and under warranty for a long time!
*During the school year I fill up once a week but I'm really hoping to cut consumption in half over the summer :)*
