Literally the worst experience I have ever had. A couple years ago I was working with a salesman to purchase a car. They needed references and my brother had just moved so I didn't know his new address and he was taking forever to get back to me so my salesman said to use his girlfriend as a reference. I thought it was bizarre but agreed. I bought the car and then received a phone call stating financing didn't go through. I return the car and then get a notice in the male from Capital One saying they approved my car loan but did not feel I was getting a good deal so they did not approve the amount. I go to Chapman Ford and purchased a car and was able to get financing through Ford Credit. Then months later ALL of my references including myself start getting phone calls about a past due loan for someone none of us knew. Leading me to believe the salesman provided my references to another client that defaulted. It took a year for my family and I to have the calls stopped.
Now on Tuesday I was downtown and then had an appointment in central Phoenix so I went in for an oil change and three people just stared at me and kept talking about some girl. I ask one of them whom I speak to about getting an oil change and he points me to the other two gentleman. One of them says he is my customer (which happens) but then only after I asked who to speak with do they start talking about a car. The first person I asked directed me to a female who sighed and ugh'ed so loudly at having to help me that I said I will go somewhere else and left.
