Went for a Purchase - things did not work out and we felt as if the Sales person FADY or whatever his name was got offended by my counter offer.
I felt like, I was not being treated well from the beginning since during my conversations with Nixcy over the phone, I always told her that I wanted to buy the NX but then I changed my mind to see the RX350 and Fady once told me - Oh, because you told Nixcy you wanted to see the NX we were preparing accordingly. Well - If the client changes their mind to see a better vehicle that should actually make the salesperson happy and not nagging about it.
Very surprisingly Nixcy, who was coordinating with me all the while on the phone to pitch us in to review the offers at their dealership in person and when we reach there she transferred us over to another salesperson called Fady. Me and the wife were more comfortable dealing with her over the phone hence the reason we went. Sometimes a client needs to see a salesperson that makes them comfy enough and gives them that confidence that they will work with them when they arrive. Anyways!
From the beginning Fady was not friendly enough to provide us the buying experience that one would like to have. In the end, when I did not agree to the numbers (which every client has a right to) since it was not fitting my budget I would have expected Fady to say good bye in a very sporting way rather than giving us that offending look. In turn, I and the wife offered to shake hands before leaving as a gesture that should come from the sales person. They definitely lost my second consideration that i would have returned home and thought about since I really want to buy one of those vehicles.
Highly disappointed!!
