I think you should take a breath and perhaps a step back. Your purpose as an evaluator is to paint a picture of the experience the way it occurs, Therefore you document the communication with the sales person much as you have done here. If there is a place in the report to give your impression or state what you didn't like you can mention it was off putting and if you were a customer would cause you to look elsewhere. If this is the policy of the dealership to put you through this, it gives them the opportunity to re-evaluate their methods. If it is the salesman, then it provides the dealership, and perhaps the salesperson, to re-evaluate his methods.
A while back I did an internet inquiry for the same company several months apart. The first email response I receive asks if my email address is a good address, and nothing else. The second response is one line asking if my phone number is a good phone number. I thought these were silly and unnecessary question since I supplied both an the contact form. It would have been easier and more respectful of my time, just to reply to the question I asked. It would be different is any of the contact information proved to be invalid, but it wasn't. The second time this happened I was so tempted to cal the internet manager and ask why she was wasting my time and hers asking for information already provided, and just answer my specific inquiry. I was thinking both as a consumer and manager of a business. This method was not good for either side. I resisted the urge and completed the report objectively. In the section that asked what I disliked about the experience, I cited the two initial responses and why I disliked them. Obviously my report didn't change anything the first time because the same thing happened on the second inquiry later. I haven't done another for the same dealership to know if any change has been made.
The point is you provide a forthright, and as much as possible, an objective report of your experience and let the business do what they will with the information. It is the purpose of a mystery shop.
