There are solid points made in this post from /u/TheAureate and there are some good concepts that carry over. Whether or not he knows this, he has basically listed how to apply PUA to a sales process for selling a car.

The one thing that I can see he missed is the simple sales process of building value in the process, not the product. The other thing I can touch on is the missing information of how he built commitment from the sales process. The customer spends so much time with you its a sunk cost to go anywhere else, or at least you demonstrated the product completely and the customer is sold on the process, not the product.

Much like a slut at the bar at the beginning of the night. You have to demonstrate that you are high value and get her to commit to you.
