Fantastic dealership with professional and courteous staff.

Mike over in the service department had great service for me very knowledgeable and took care of everything that we needed to.It was great service

EXCELLENT!! Best car buying experience EVER. Jerry is educated on the vehicles, is kind, knowledgeable, considerate, listens. Seamless transaction and fantastic deal.

Customer service was good. The time line of my truck being complete was later than expected but okay cause Mike was honest with me and kept me in the loop. I truly appreciate that.

Very helpful. they are there to assist in anyway possible to make your experience pleasant.

Peter was awesome and easy to work with! Would definitely recommend speaking with him when looking for a vehicle.

The prices attracted me. The customer service and experience/ level of knowledge was not great. There was an inconsistency of dealership policy. It would be nice to get a car for the price you expect. I felt forced to purchase items I did not want

Professional and superb customer service. Was dealing with a check engine light. They go out the way to make sure customer is taken care off.

We were happy with the service and time it took to complete our purchase. A sales rep (Jerry) worked with us over the phone and had many documents ready to go and prior to our arrival.

Dealer add ons are extremely high, we were able to work on some of those numbers. Still high after bargaining, but I agreed since I wanted this truck. When Mariah came back with financing option, I come to find out that we can't finance outside, it has to be their financing or pay cash! Can you believe this? After everything done with salesperson, had to wait for finance. Sat for over an hour &1/2. Employess kept walking in & out of finance office, some eating, while customer just waiting.

Staff was friendly but i left without being able to have my app hooked up to my car and I was looking forward to that feature

Had to get some warranty repairs done. Jeff took care of all the processing and we were informed about the progress from start to finish. Professional, courteous customer service.

I had an amazing experience yesterday at Tustin GMC & Buick with Seth R.. I called him the night before to ask about the Sierra EV 2025, and he got right on it! We got the deal done in minutes, charged up the truck, and it was waiting for me to pick it up the next morning because I couldn?t make it that evening. This dealership is incredible! I usually buy luxury vehicles, and the service was just as great as when I do business with Porsche or Land Rover. George in finance was nothing short of amazing as well. The management is doing an incredible job keeping them going because they have such a great team. Every turn was met with a smile, and even in workout clothing, I felt like a valued customer. Thanks to Seth and George, this dealership is now my new pick-up truck home, and I?ll definitely be buying my pick-up trucks through Tustin GMC & Buick in the future.
