I don't think there's a "mileage counter" on this machine. I can tell you it's a good one, though. I inherited a Rose 500 from my stepmother when she died. She bought it new, and I've used it for the past few years (one of 5 machines) and it sews beautifully. You've got a good price there for the whole package. Will the family let you have it looked at and tuned up before making your decision?
