Here’s the closet representation I can conjure in calc: leasehackr.com/calculator?make=Chevrolet&miles=12000&msd=0&msrp=44640&sales_price=40935&months=36&mf=.00001&dp=0&dealer_fee=85&acq_fee=695&taxed_inc=11250&untaxed_inc=0&rebate=0&resP=53®_fee=400&sales_tax=8.25&demo_mileage=0&memo=&monthlyTax_radio=true&gm_onePay=true

Decent, but you can do better, imho…Bay Area folks are already at 10% off and better, with no work.

edit: your tax rate should be corrected above, it was left over from my tax rate…doh…and that gives exactly $8719…I would take it to 10% off, and float that over to dealer, they are hungry to get it off the lot.
