Ask them how much principle (down payment) is in the first months drive-off charge, then put it into the calculator; a 10 year leasehackr score is a good deal or less than 1% of MSRP (which is a 9-yr time to repay MSRP including taxes in a high salestax state = 109%) which is a little worse, per month.
That is better than I was quoted this week. I was looking at a GLE 350 4matic that MSRP’ed at 67400, with zero down 36/12000 they quoted a staggering $950 a month.
They gave me the MF and residual (.00068 and 53% respectively) I could not replicate the lease in any calculator. When I asked them to explain how they got that number, they refused and stopped responding to my emails.
