carfax will only report u the miles u report to the DMV since last owner, NOT current so nobody really knows the real miles on the car. u can pay $35 to someone at least here and u can take off or add miles whichever and is illigal as they said even if u add no matter how u see it is illigal. a 94 accord there is no way it has 35k, 85k sounds ok 2 yrs ago my car had 50k and is a 96 accord now has 80k. if i were u i would just fix it at 85k and sell the car. since no one knows the real miles and most likely the dude before u was messing with the car, i would just sell it before u have to spend hundreds of dollar.
