I am trying to understand the scenarios where it makes sense
I don’t understand the points where after 4 years of payments your remaining payments will be small compare to MSRP like 20% residual, I don’t think that 20% put in residual by contract. So it does not make sense for me to consider a lease at all.
for example, scenario 197k msrp - 160 sell price - 10k down and 4.99% APR finally it will be 40k cheaper after 48 months
Some vehicles are great lease candidates, some are not. Some vehicles are great for purchase/finance, some are not. Then you get into the personal finances and/or applicable business scenarios..which can also vary.
There is nothing that says leasing makes sense 100% of the time.
