With a 26% discount from sticker the dealer almost certainly has any incentives rolled up in the discount.
The discount is very strong, however they are offsetting that with a MF marked up to the max and $658 in garbage add-ons and an acquisition fee that appears marked up as well. So take that into account.
Really need to plug all this into the calculator and see exactly what the discount would translate to at buy rate MF and without the garbage fees to get a good idea.
Playing with the calculator and backing it out to buy rate MF and accounting for the add-ons it’s still around a total 23% discount including incentives which is very strong on a M340i.
Normally I’d say take that out of the deal but with a discount that strong, who really cares? This offer has 6 months of payments built into the front end.
