The cheapest S650 Mustang to lease is the EcoBoost over a 48-month lease term that averages around $503 per month.
"To start, the 2024 Ford Mustang EcoBoost (MSRP $32,515 including destination) is listed at $491 for 36 months with $3,743 due at signing and 10,500 miles per year of driving. When you factor in both the payment and amount at signing, the effective cost of this lease comes out to $595 a month before any taxes & fees.

For the money, that could seem absurdly expensive to Mustang fans. Having said that, Ford doesn't exactly make it easy to spot the car's high cost by defaulting to a 48-month lease online at $426 per month. However, even with $3,678 due at signing, the cheapest 2024 Mustang costs at least $503 a month to lease."
