Okay. So my new, used Buick regal had the odometer gauge out. I assumed it had 170,000 from the carfax report I purchased. Today though I fixed the digital odometer and it read 108xxx miles. Should I be jumping up and down like a happy little girl shrieking? or should i discredit the car fax and the dealers estimation. I have no idea how long the light has been out for, but i imagine even though the cluster has been out, the computer would still accurately read the odometer. Wouldn't it? When I was driving today it was still reading right going up a mile on a road I know is only a mile long and so on.
