I thought you might be joking at first, but from the article: “I don’t know if it gets better gas mileage, but I like her car because it costs $100 to fill it,” said Ms. Hammond, 40. “I think $100 for a tank of gas is cheap now.” So as long as it is less than $100 per fill up, she doesn't care what the mileage is.
