It is not very easy to roll back mileage on a BMW. The mileage is stored in 2 places, the instrument cluster and also the lamp control module. Because of the redundant storage if someone simply replaces the cluster then a fault is stored and also a manipulation dot is displayed in the cluster. (small red dot next to the mileage display.) Of course it is not impossible to do , but it takes special coding equipment so only a higher end criminal would invest the money in equipment. Its not as if any Joe Blow can easily roll back mileage without any trouble. That said, as Peter said, Carfax is a great tool as well as looking for the maniulation Dot and of course using common sense.
