Camelback Ford Lincoln

I was looking for the 2014 Ford Mustang V6 in manual transmission. There is limited inventory left in AZ for manual transmission, so I went to Camelback Ford because I was interested in a particular one I had checked up. In spite of having read the negative reviews about the customer service, I headed there to try my luck. I was wrong. I go there with an OTD price quote that I had already received from Stephanie, their internet sales manager. I work for Intel which makes me eligible in the X-Plan discount program (little discount over the regular price). I test drove the Mustang that I was interested in and then sat for the price quote. Firstly, I got tired waiting there at each of their move - getting the car up for test drive, getting in the quote, re-quote after telling them this is not the price I got in the email, waiting for the internet manager to actually show up after having had fixed an appointment with her. I then tried negotiating the price for any 4th July specials. Negotiation is a part of any car purchase deal. Who doesn't try to negotiate the price? The internet manager, Stephanie, told me they cannot negotiate on the X-Plan pricing and was adamant on that. I was still trying my luck for a few minutes. Then out of the blue, she threatens me with, "Give me your X-Plan PIN, I'll complain that Intel employees (a friend was with me) are trying to negotiate X-Plan price and they'll take some action". I pulled out the X-Plan terms and no where was it mentioned anything that you cannot negotiate. We asked her show us where it is written. To which she said I have not read it, and added, "I said I might complain, and not I will complain". [non-permissible content removed]! Clearly she had threatened us and was trying to step back from what she had said. If you cannot bring down the price stick to that and I'll take the deal or reject it. Do not bloody threaten me. That is not how you talk to customers. We walked off from there. I cannot deal from here if you cannot talk properly to customers. Keep your cars! I will be reporting this matter to their manager.
