I agree, it is a long story. But it's the details that really make the story of going undercover as a car salesman what it is. For instance, a salesman might ask a prospect the price they're willing to pay every month. After the prospect comes up with a number ("uh, $300"), the buyer says, "Up to?" ("Well, up to $350."). It's all about the insidious little details.

Furthermore, the concepts here can be applied to protect oneself against rent-seekers in general, including salesmen of all kinds, lobbyists, marketers, and some VCs. It's a three-hour read, but I found it was worth it.
