OP ask for the internal dealer service records for the vehicle. Every BMW dealer has access to these and it will tell you which services were performed and at what dealer location. They will not certify a car if it has not at least hit the required maintenance intervals so unless the dealer is acting in bad faith, I wouldn't worry about carfax not showing the services (it's quite common that carfax won't show the entire history) I'll PM you mine.
