The people are nice But i had an appointment for 10 am and when I got there on time, they were extremely busy and short staffed and said my routine oil change would take 2 hours at least. The lobby was and when I got there on time, they were extremely busy and short staffed and said my routine oil change would take 2 hours at least. The lobby was full with no place to even sit. I have a heart condition and cannot stand for very long. I had to reschedule for several days later. I drive 30 miles round trip to get there and with gas so expensive I was not happy. When I came back for the rescheduled appointment, I was worried the same thing would happen but the service went well and didn’t take too long. The lobby was full again however and I sat in a hard chair right next to the door that is usually used at the desk of the workers for the customers to sit and sign in the car. More

Worst service I have ever had, charged me $1700. 6months ago for the same thing wrong now. Not really mechanics, just technicians. 6months ago for the same thing wrong now. Not really mechanics, just technicians. More

At almost the end of my truck warranty, the phone charger never worked. The regular driver took me home. They ordered me a Lyft to get back to get my truck. Now it works!

This will be the third vehicle bought at this dealership (we bought our last two vehicles when it was Rally), and it will probably be our last. Our salesperson, David, was great for the first day. We ende (we bought our last two vehicles when it was Rally), and it will probably be our last. Our salesperson, David, was great for the first day. We ended up working with a manager (I think it was Javier) who was trying to get our business when we initially tried to leave. He came running out asking what he needed to do to gain our business. We told him the price was too high and told him what we could afford. He ushered us back inside, but it was a big waste of time, as the payment was still way above what we could afford. When we left the second time, he called us and wanted us to return to complete the "deal". It was late, so I told them that we would come back the next day. He said that he would send someone to our house that night to complete everything. I said no, we would return the next day. I called the next day and found out that David had a death in the family so they passed me on to Jonathan who didn't have a clue what was going on. It was phone tag and text messages most of the day, as I initially called at 10:30am. A lot of times that I called I was told to call back because Jonathan was not at his desk. Other times I would speak or text with Jonathan, but never moved forward with anything. He asked for a copy of the drivers license at 12:25pm, and then was notified at 2:32pm that the vehicle we were looking at had a dead battery, and would not be fixed until the next day. I asked if there were any other colors available besides black and he said "Yes there is other colors available", but nothing else. Did not hear back until 6:56pm when he sent me the link to the credit app. I had issues trying to complete it on my phone, so he called me and took the information over the phone.. By now it is 7:52pm, and I was told that they would not be able to get final approval from a bank until the next day since it was so late. Never should have taken all day to complete the sale. We went in the next day and they had put in a new battery in the vehicle, but the down payment and monthly payment was completly different than what was discussed with the manager and David, even though Jonathan had confirmed with me, by text, that they would honor the numbers that was agreed to by the manager. (The manager was not in when we came in to finalize the sale, and they could not reach him by phone). After going back and forth, again, they finally agreed to the same numbers and we moved forward with buying the vehicle. We only had the vehicle for a few days, when were called by Jonathan to tell us that we needed to bring the truck back in because he forgot to set up OnStar, and there were two active recalls that had not yet been completed. I don't understand the recalls not being done, as they came out in April. This definitely should have been completed prior to selling the vehicle. We only have one vehicle, which my husband uses to go back and forth to work, so dropping the vehicle off and losing a whole day without a vehicle is not an option, especially when it wasn't something that we were expecting to do. I asked for a "loaner" car, and was told that they do not do "loaner" cars for recall services, even though they needed the car for the whole day. My whole experience with Diamond has left a very sour taste in my mouth and I am not sure I would ever buy another vehicle from any Diamond dealership in the future. If you need any further details, you are welcome to give me call. H. & Y. Nguyen More
