Ditto that. I live in Maryland and leased two months ago. My sales manager was pretty upfront about the financial process - that $209 / $2300 down is just an "example" - they will use the same money factor (i.e. interest rate) and generate a lease number for any amount you want to put down. You can still negotiate on the sales price used in the calculation (though mine claimed that the lease already required a concession from the dealer so there wasn't as much room to negotiate as there was against MSRP).
As a data point, after agreeing to a modest reduction in price, and asking for 15,000 mi/yr instead of 12,000 (those are the only two choices for promotional leases, though) - which cost me another $700 as lower end-of-lease value - I came out with a lease at $276/mo with only the taxes and dealer fees paid upfront, about $2250.
The promotional lease uses a cost of around $23,000 after EV credits, a lease-end value of $14,400 for the 12k mi/yr version, and I worked out that the interest rate being charged is about 1.2%. I considered those pretty good numbers and this deal is part of why I so quickly chose the Clarity over the Ioniq EV or the Bolt that I was also looking at. (On paper the MSRP of the Ioniq is less but I'm not sure it would come out cheaper on the lease.)
By the way, I was told that in Maryland we pay sales tax on the entire vehicle value upfront for a lease, but then don't have to pay any sales tax if we buy the vehicle at end-of-lease. If anyone has had a different experience in Maryland I'd like to hear about it. (I know other states do it differently.)
One other thing - I did consider paying a lump-sum lease but decided against it. This is my first time leasing, and I had some uncertainty about how the money will be handled if the car is totaled or the lease otherwise gets terminated. I didn't want a potential situation where I had paid more than the depreciation on the car and didn't get it back. And at 1.2% I consider that almost free money - the difference from what I am earning in the bank is less than the value of keeping ready cash on hand for other needs, IMO.
