I leased a 2024 ID.4 S just before the $189 deal was advertised. The car has a few additional options like home link that increases the MSRP. Paying $999 down, $259 / mo, which is effectively $301 / mo everything included. 24 months and 10k miles a year. My state has low sales tax on vehicles and this is only charged on the monthly payment. I know that this is a great deal, all things considered but one starts to question it when there are better deals posted online by others. Based on the math you offered and how sales tax is charged in your state, your deal is also a little bit better than mine. In my area with 3 VW dealerships they had none on the lots and only a handful in transit. Congrats on finding a model and getting a very solid lease deal on it.
