People way underestimate what it costs to drive their cars. You have to consider way more than just gas and an oil change. I know I track what it costs me to drive and the costs isn't much less than the goverments rate per mile for bussiness (currently 0.555/mile) and drive a fairly cheap car and keep them for a long time.
A car does not last forever and using 2200 miles will shorten the life of the car by that much. A care is usually good for 120-150K before starting to have major problems (I know some would argue with me on this). If you pay $20,000 for the car and it goes 150,000 miles without any repairs that is 13.3 cents per mile right there. If you finance or even if you didn't, you need to consider the value of money over time so this will go up.
Even with a car lasting 150k miles, you are going to have maintenance and repairs. If you can do them yourself and you have the time, the cost will go down. Not only $30 for an oil change, other fluids, belts, hoses, tires, brakes, battery, wipes, lamps, cleaning, and other preventive maintenance items. You may even run into other major repairs that you need to perform. Even the "good" cars that people sware by have problems. Over the life of the car, theses costs may equal what you paid for the car but most likely will exceed.
You do have some fixed costs but I feel you need to include them in as well. Some say insurance is a fixed cost, but this can go up or down depending how much you drive. You have registration, inspections, taxes, etc. that a little to the cost. When adding up what it costs to drive, these costs are very minimal and only come to a few cents a mile.
