Just an FYI: you're driving well below the average annual mileage while getting better-than-average mpg.
These are not typical numbers for most people.
Your annual mileage: 10572 at 24.6 mpg =429 gallons annually
average car: 12500 at 21.5 mpg =581 gallons annually
average light truck: 14000 at 17.2 mpg =813 gallons annually
(average numbers pulled from the EPA.)
One of the deciding factors in my getting back into bicycling and working towards parking the car permanently was having to get new tires, oil changed, and a minor repair (a grease boot replaced) in the same month. In one week I dumped $650 on my car. That's not including my monthly fuel expenses: about $150-200 at 25-ish mpg. (Subaru Forester)
Yeah...car-lite is a no-brainer for me. Even allowing myself a tank of gas (~300 miles) a month, I'm still saving about $6-8 a DAY.
Several of the minimalist sites and the like that I frequent use $8000 annually for the average cost of owning a car in the United States. From my experience, that's about right.
