I'm just thinking that it's quite expensive to fully fill up an SUV or a van. My dad has to commute everyday to a city 30 miles away, 5 days a week. that's 300 miles a week on that alone, not including when he goes to the cities (Minneapolis/St Paul, ~90 miles away) or goes to other cities for stuff. One tank of gas for a Toyota Sienna usually takes ~$50 to fill it full.
