You have to go fishing. Just because one person on this forum got a deal, does not mean it is easily available to the general public and they can require work.
You might also have better luck calling in and asking for the new car sales manager or general sales manager. Or if you want to email, find the email for the GSM and CC the GM and/or the new car sales manager.
When I hack for myself I always email an SM or GSM. That way, when I lay out my whole deal, they understand it immediately, and it’s a binary yes or no, either they will do that to move the unit, or no, they would not like to. Hacking thru a salesperson is miserable and I wouldn’t recommend it.
(Important here is that I always make it clear, as I’ve said, that if they say yes I am willing to do a credit app/deposit immediately)
My last lease was done via an internet person who was running the negotiation details to the SM. When we finally got to an agreeable deal (about a 10 day process) and I came in to sign, I was turned over to a sales rep who bascially had very little to do except baby sit me until it was time to go into see the F&I guy. He likely got a “mini” or “flat” deal out of it but he didn’t seem to mind since I took up almost none of his time or effort.
Fear of low payments. It’s a disease that effects many car salesmen when they’re unable to actual put lease numbers together themselves. Tends to spread at times when the leasing planets align to make for abnormally good terms. There was a jaguar f type variant in 2017, Volvo s90 variant in 2018, bmw 4 series one in 2019, chevy bolt last year, and apparently a camaro version now.
