I was actually going to make the same recommendation as 2). First of all, it's a great bellwether of whether you want to work with the salesperson at all. If they know you are buying the car, but they talk to the man you bring with you, you know you want to go somewhere else or work with someone else. And if you only have one salesman to choose from, at least a salesperson's misogyny won't cost you more.
