Where can I find a reliable source for a car when it comes to its history? I have already checked carfax and am satisfied. But I want to know the repair/service history. The cars in question, 2001-2003 M5. Will I need any other info besides the vin?

Thanks guys...

I thought you could check the dealer for the maintenance history... Unless this vehicle has been taken to non-BMW maintenance facilities then probably not much you can do. Major repairs should be on car fax, but minor ones probably difficult to obtain (which should be ok because it is not material).
