You have to start somewhere...

There were approximately 12.7 million new vehicles sold in the US last year. The average number of miles driven last year is down from the 15,000 that is typically used to 13,476. I suspect it maybe harder to get numbers on used vehicles versus new vehicles. My FIL has a 1984 Chevrolet pickup that he has owned for over 20 years, annual mileage is ~2,000. I am sure there are a lot of similar vehicles around. But I would say the bare minimum to have a car and keep it road worthy is going to cost an average of $100-$150 a month, if you drive it the costs go up.
