That is horrendous, these were leasing well a while back. I’m not sure if the numbers went really bad for the Giulia or the dealer is just trying to bend you over a barrel. You can get a loaded 2021 540 for this much.
You’re in PA? Talk to Justin Sutton at Fiat of Erie. He has a post in the marketplace, I got mine from him 2 years ago, best deal hands down. Reach out to him.
I know rates change, but as a reference point: two years ago I got my Giulia TI Sport AWD ($50,190 MSRP) for $371/mo (base pmt) with just normal up fronts DAS (~$1800).
Your MSRP is higher, but +$328/mo over my deal is horrendous.
