Here’s the closest I can get to your Calc. I believe the minor discrepancy is Florida’s county discretionary tax, so I adjusted the cap reduction (down payment) to reflect the up-front tax, but its pretty close.
Definitely listen to others who tell you to read up and confirm rebates, RV, and MF with Edmunds. However, I believe the lease cash # is correct, and the MF is almost as low as it can get (0.24%). I can’t confirm the RV, but I believe it is in line with other current Lexus models in the low 50s (Dealers tend to not fudge with the RV, as they don’t set it themselves, but confirm the 52%)
At 10.5% pre-incentive and the fact that you’re leasing at close to 0%, this isn’t bad in the current market. FL dealer fees are always killer, but they haven’t stuck you with any add-ons.
If it’s the car you want, go for it.
