Not quite
Adding on to Jon’s point: Edmunds is the sanctioned source that will tell you what the captive (e.g. BMW FS) residual and buy rate MF are. As long as the dealership is using the captive lender: that is the residual (can’t be changed), the MF can be marked up. You are eligible for any incentives you are eligible for, but a shady dealer could obfuscate those in the deal so you want to verify those (Edmunds or Autobytel). The pre-incentive discount is the only negotiating point, assuming they are not marking up the MF and passing on all the incentives.
The lease programs change every month — in a few days November programs fall-off and it becomes a December to remember / Happy Honda Days (whatever you celebrate), so you will have to verify the programs again if you are still shopping. And occasionally some incentives might not change on the month (e.g. OL codes have their own expiration date).
If you are targeting BMW may I suggest
