We have a suv because it is 4 wheel drive and we need that around here, what with a lot of our roads being no winter maintenance. However, my next car I would like to find one better on fuel.
I am okay with needing fuel for things like generators and reasonable vehicles but I am also pro wind power and solar power and being green.
On topic, I fill my car with the gas points and in the summer, we fill the gas cans for the lawn mower. Our gas stations reward points are 20 gallons.
