It varies a lot for my car; the fuel costs are <10 cents/mile but for example I barely drove it at all this winter so the fixed costs like registration and especially insurance costs/mile were horrendous (unfortunately a person needs to carry coverage on something continuously or else the insurance companies rake you over the coals when you want to get back on) but if I drive it more the insurance costs/mile go down. In fact this winter I paid more than double the cents/mile for insurance than I did for fuel and I doubt anyone has cheaper insurance than me!!!
Maintenance and repairs are virtually nothing as I do 99% of the work (the only thing I hire out is tire mount/dismounting) and I use scrapyard parts when possible and besides, it's a Ford so I don't have to work on it very much.
