Def worth a phone call of suspicious activities. Good read, I would be very upset purchasing a car from a “salesman” who was a liar and knowingly sabotaged a car for better re sale.
Some people just swap clusters. Some people try and get away with it because if the car is older than 10 years in Nys then it is exempt from reporting the mileage on the title when you register it, so it’s far more common on vehicles over 10 years old.
I suspect if you’ve got basic computer knowledge rolling back a digital cluster is easier than a mechanical one.
