I would be surprised ... the OBD-II info is usually just the current reading. It does not keep old info.
Your best bet is Carfax. The Infiniti dealer in your area can also look this info up ...
Sometimes, the insurance agent can do it too - particularly if the car has been insured with them from the start. They keep track of usage because the insurance cost varies depending on how much you drive. Also, my State Farm insurance web site allows me to look at mileage history - as reported by the dealer at service times (I think they are required to do so by law), and my own self-reporting mileage, etc., to Carfax.
