2020 RX 350L deal check

Hi guys, new to the site. Was wondering if you could help me on this deal.
I’m currently leasing a RX 350 which is due I. June and looking to upgrade early the L for my wife.

My current payments are $550 per month with 2 payments left and I am over mileage by about 3k costing 0.25 cents/mile. They are willing to absorb the payments but I would have to pay the excess mileage and zero drive off otherwise. Any help would be appreciated. Thanks!

This is the best I’m getting so far but not getting the numbers to add up on the calculator.

Their numbers are just about right on if you roll in those last two payments from your current vehicle rather than assume they’re eating them.
