As you're walking into a bar or club, pay attention to the parking lot. Look for a car you like, in fact, you dont even have to like it - just make sure it looks like something a woman might drive. Go into the bar / club and walk up to a target and ask "Excuse me, do you drive that blue Toyota Camry?" It doesnt matter if she drives that car or not. If she says it is hers, tell her you're thinking about buying one yourself and ask her how she likes it. If she says it is not hers, ask her what she does drive. If she does tell you, then you can make up a story on how a friend of yours had one of those and thought it was a piece of shit, or whatever. Whatever you want to say after that. I havent tried it yet, but I look forward to doing it. How to escalate things from there, I'm not quite sure, but I'll think of something.
