Yes, MACO & Training Fees are added to the Invoice Price, not the MSRP. If you are negotiating based on how much off MSRP, then you don't need to worry about it. But if you are negotiating based on Invoice, then MACO & Training Fees are legitimate fees added to the Invoice.
Some websites like Edmunds and Kelly Blue Book do not have these fees on their Invoice calculations and it is always a problem with people unaware of these fees. Bimmefest members are more informed, so it is never a problem.
