Hey Wilso566- Take a look at some of the new non demo cars listed by brokers like Avocautos on the West Coast who recently had a stunning new 7 series M-Sport that was over 20% off pre incentives or East Coast like NYCLIFE who has a 740xi at 20% off on his spreadsheet and others. Of course demos have been less.
Again, only mentioning to highlight what might be considered close comps by other members of the forum and not to throw shade on your deal.
outside of the power difference… are there any real big things the 740 is missing in comparison to the 750 that are worth hundreds per month difference? Most on this forum will say no… but maybe you have different thoughts.
