Might be interesting to get printouts of the service records, since they must exist for the repeat visits - not sure if its possible for you to get them.
Keep in mind that CARFAX does not update right away, so check to see when the car hit their lot.
Also, BMW do buy backs to avoid having the car show up as a lemon. After the buy back, they put it on the lot or bring it to auction. A buy-back won't qualify as a CPO car. That alone would make me second guess they went through the effort/cost of buying the car back when nothing is wrong with it.
