You probably don’t remember this but you coached me when I was an LH newbie before I walked into an Infiniti dealer to work out a deal on a Q60 RS. I got the deal and the rest is history but I can relate to OP, even if he is trolling, to the sense of empowerment you get from negotiating from a place of knowledge.
edit - I will add, I do think the brokers here are a HUGE source in empowering people to understand what is possible. I would imagine most of us at least benchmark what the market looks like while prepping for a deal thanks to brokers who openly share deal sheets. Community members and Trusteds may provide additional clarity, but when you are new and trying to get your head straight, it is so, so helpful.
