I have filed complaints with CarGuru, BBB, and the State Attorney General's office regarding this matter. I took those actions only after trying to work this out with the dealership and getting nowhere. On 9/14 I worked out a deal with Augustine Gomez to trade in my Mercedes E400 coupe for a Nissan Maxima sedan and $4K. The additional cash was due to the imbalance in value between the two cars. I had an appointment to keep, so I told Augustine that I would be back later that day or when they opened the following morning. The used car manager, Ron, tried to get me to stay and finish the deal, saying he could cut the check immediately and get me on my way. But I had no choice. I had to leave. I was there the next morning at 9:00am. The Maxima was ready for delivery. Augustine and I started the paperwork. I quickly noticed the terms had changed. The $4K difference had disappeared and now I would have money owed to the dealership. I asked to see Ron. He was not there. I was now dealing with Mike, and his opinion was that I had been mistaken. Now the deal was off and I should have left. They offered other vehicles that were of noticeably less value. I repeatedly said no. Then they offered a used Impala. The car had readily visible issues and defects that need repair and attention. I told them, I would make the deal if they would give me a loaner car and repair all of the issues that existed on the Impala. Mike said No. His position was that I had to take the car that day, and I could bring it back sometime in the future for service. I took the car. When I got home, I started inspecting the car more closely and realized there were more problems with the car than we originally discussed. I called Augustine immediately the next business day and said I changed my mind and the Impala was in no condition to be delivered as a used car. He said to bring it in the next morning. I was there at 9:00am. I pointed out all of the problems I had found. I asked everyone to allow me to speak to a General Manager or Clay Cooley. They said No. I again asked for my original car and cancelling the deal. They refused. At that point, they offered a loaner car and they would turn the Impala over to their Service Dept. I didn't want the car. It had too many problems. I asked again to speak with the GM. The Finance Manager came out to speak with me. I went over the entire experience with him again. When I told him that Clay Cooley sold a car that had not been fully serviced, had not been inspected, and had not been detailed, he replied that can't be true. We (Clay Cooley) put every used car through an extensive 171 point inspection before they are allowed on the lot. I said to him, "Not this car". He said I was wrong, and he went to get the inspection sheet evidence. He never returned. There was no paperwork. Mike still would not consider/allow the deal to be cancelled. But, he offered an alternative. There was another Maxima that was not as well equipped or valuable as the one I had originally agreed to purchase. But, if I decided on that car, I would forfeit the $4K that was part of the original deal. I was in a corner, and had no negotiating power. I test drove the car. The vehicle made a loud low pitched sound when accelerating to cruising speed. I mentioned it to Augustine during the drive. He didn't hear it. I said it could be the road, but I believe it's in the car. He said everything seemed fine to him. I took the car home. The next day I drove the car and the low pitched sound was still there. I drove straight to Nissan of Fort Worth. They took the car and called me a few hours later. The car was unsafe to drive. The wheel hub assemblies and bearings on the right side were damaged. Continued driving could have easily resulted in an accident. I once again contacted Augustine with the information. I want to come to an agreement with Clay Cooley. You have sold me two cars in one week. Neither of which did I actually want. The first car was dirty, damaged, unserviced, and uninspected. Yet, your internal procedures allowed your used car staff to push it towards a senior customer, assuring him everything would be taken care of at a later date. Then you replace that vehicle with one that has serious/dangerous mechanical damage that is audible to a senior customer with limited hearing, and verified/repaired by a different dealership's service department. Can we go back to square 1 and do this right?
