Just found a deal on Edmunds Price Promise for the Maserati Ghibli Base ($74,725 MSRP) for $241/month and $6,441 total due at signing. Total lease cost is $14,876 which comes out to $419/month.
It's only for 5k miles/year but in the past this same car has been going for between 5-600 per month with money down. The best I had ever seen was around 500 or so with 0 down.
This was found in Southern California so YMMV
Make sure to filter on the side for lease, and you can sort it by price.

Historically Maserati of Anaheim Hills has the best deals but when I checked their site they are offering the same car for $439/ month with $4,888 drive off.
