Upfront taxes on the incentives/cap reduction, acquisition fee, registration fees, dealer fees, and rent charge all get rolled into here.
You gotta stop with the confusing hypotheticals back and forth, selectively leaving out some taxes but not all, etc.
What’s the car? What’s the discount? What’s your tax rate? What’s the mf/rv/incentives?
Rather than try to back calculate some crappy dealer offer, just work out a target deal for what this should be. Even if you work out exactly what the dealer offer actually is, without a target deal to baseline against, it’s useless information.
It looks like you know how to calculate things, so here is what I received from another dealer. Let me know how you calculate or suggest what other details I’d need to get from the dealer
The calculator you get by paying $6 for a month will tell you exactly what MF and program discounts/rebates you should be getting for your exact zip code and trim. It is a no brainer purchase if you are about to lease a car. Using it will answer a lot of your questions here and prepare you to make logical offers to dealers.
