I have a "guy". I call him tell him what it is exactly that I want along with what it is I want to pay and he goes and finds it for me. He calls me back and let's me know when everything is ready. I drive down there, swap vehicles and sign a few sheets of paper. Total transaction less than an hour. When I purchased my last truck he actually drove it to my office with the paperwork and took my trade in back with him. I refuse to play the standard dealership salesman game.
I bet your guys is a car broker. My neighbor was a car broker. I'd never heard of that, but when my car died a few years ago she asked what I needed and how much I could pay. She then negotiated the entire deal for what I wanted to pay. I knew my payment, trade-in, etc going in. The dude had all the paperwork ready. I was in and out in no time.
My last lease she took my old VW, and came home with the new one while I was at work.
