Yikes! Well thats not a good thing to find out. When you registered the car they didn't give you any flak at the DMV for having inconsistent mileage? I know in my state that they check for odometer consistency - if you are registering the car for less than the miles last indicated at inspection/registration renewal, you can prosecute the previous owner for inaccurately representing the mileage. In the back of many titles (transfer section) there are check boxes that acknowledge that the mileage is not actual and/or has been reset. See if you have the designation on your title and just missed it on the sale (there is usually a letter in the odometer box, ours is A for actual, another letter for other).
