I previously looked into the average cost per mile of car ownership, after hearing the IRS values it at 58.5 cents/mile, and came up with this breakdown ($7,605/yr):
"The average vehicle costs $40k, is owned for 11 years, gets driven 13k miles per year, burns 25 mpg, gas costs $3/gal, insurance is $1500 per year, and the vehicle needs $900 per year in maintenance and repairs."
The Bankrate estimate seems high, but not by much. My own cost is 38.4 c/mile.
