As a person who earned a living based upon a 100% commissioned sales job for over 50 years, you learn that one of the very basics is to NEVER put down what a prospect currently owns, or a competitor’s product if he/she has been considering that.
Instead, you compliment them on their current or prospective choices by saying ... "I understand why you would want to go that way, ABC makes a fine product. However, our XYZ offers as much if not more. Let me explain ... " Then you proceed to point out the features and benefits of your product, and then try to close the sale.
If you insult the existing product or the prospective product, you are insulting the intelligence of the prospect. After all, it is HIS/HER choice, right? This is called "sales 101."
We’ve all suffered putdowns by condescending salespeople. Based on my experience, I am always critiquing salespeople and judging their skills. Back in the early 80s, I was driving one of those big Oldsmobile Broughams. It was fully loaded and in excellent condition as it was used to transport clients.
I walked into a Volvo dealership one day considering trading in the Olds for something smaller. The salesman asked me what I was presently driving. I pointed out the window at the Olds. He condescendingly said ... "Oh, you’re driving one of those dinosaurs!" My response was ... "Yes sir, and you can be assured that I will not be driving a Volvo."
