I am looking to buy a new car, and with the high price of gas these days I want to get one with the highest gas mileage rating I can. I need to get a minivan because I need to be able to fit in three car seats since we have three little kids, and I know these don’t get great mileage, but I want to do the best I can for mileage. Where can I find out the gas mileage ratings for different cars to give me an idea of which cars I should give a closer look when I am shopping?
