FL Mazda CX 5 2018 Sport + Mazda Loyalty


I’m getting ready to turn in my existing 2016 CX 5 Touring lease and want to arm myself better for the negotiations. I am looking at stepping down to the Sport trim as the only reason I went for the Touring was because of blind spot monitoring (standard in Sport now)

Model: CX 5 Sport 36/12
MSRP: $25,125
KBB Fair Market Range: $23,768 (Only 5% less, has anyone negotiated lower?)
MF: .00018
Residual: 58%
Lease Cash: $1390

Calculator: leasehackr.com/calculator?make=Mazda&msrp=25125&sales_price=23768&months=36&mf=.00018&dp=0&doc_fee=80&acq_fee=595&taxed_inc=1390&untaxed_inc=0&rebate=0&resP=58&reg_fee=400&sales_tax=6&memo=&monthlyTax_radio=true&miles=12000&msd=0

This brings my monthly payments to $255. Is this a realistic goal? Considering I am a current Mazda lessee, can I get away with pushing for a lower MSRP?
