What is the name of your state?What is the name of your state? Ohio. I live in Ohio, but I purchased a car in the state of Michigan. I have owned the car for one month now and out of curiosity I ran a carfax and found that the car I bought has a potential odometer rollback. Is this illegal and if so does anyone know what I should or could do about this? I'm really disappointed because I thought I was getting a car with what looks like about 22000 less miles on it then it actually has! Thanks, Disappointed
