That mileage isn't that rare. Check to see where the last owner actually lived. My last home was in a small town, so we barely put $10k a year on the cars even with both of us working. Shoot, I was 3 miles from the office. If it wasn't a "travel" vehicle, or just a house wife vehicle for going to the grocery, that's quite possible. I would be more concerned if it was wrecked.....
