2017 Sierra Denali deal

I’m trying to get a Sierra Denali, I’m flexible on Features. This is the best offer I’ve had so far here in Florida. Thoughts?

2017 Denali 4wd
$59,440 MSRP
55798 selling price
67% RV
.00147 Mf
$489 a Month plus tax
2368 due at signing

Another dealer has offered the same MSRP truck for 499 with zero down but he doesn’t have one in stock so we would have to work a deal on a different MSRP vehicle. Still waiting for that quote

Didn’t GM stop leasing 2017’s?

Could be US bank? (USA USA 20CAR)

I’ve had several dealers provide similar quotes. So not sure
