There is actually a special tank badge you can earn from BMW if you submit proof your odometer has re-zeroed itself by maxing out the mile count. My odo only has 5 digits, so every 100k, it zeros. Im sure its been turned over a few times, no way its only ever seen 56k miles.
I feel like ive seen one of these before, just once. Or it might be a legend I heard at a rally. Can’t remember now… Pretty sure its true.
