Tustin Buick GMC review
I had an amazing experience yesterday at Tustin GMC &
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.

My experience at the dealership was excellent from start
My experience at the dealership was excellent from start to finish. Abraham greeted me right away, took the time to understand what I needed, and answered every question with patience and detail. The entire process was fast, smooth, and professional. I truly appreciate his outstanding service and the overall efficiency of the team.

KEEP UP THE GREAT WORK AND CUTOMER SERVICE
Adam Miller in the service department is the best! He is always very friendly, and makes sure my vehicle and I am well taken care of. It seems that nothing has changed at the dealership since it was sold. I am very happy about this. Thanks again for the great customer service!

Laguna Niguel GMC review
Got my new car!
On April 6, 2023, I took delivery of a 2023 Yukon Denali Ultimate, which was a SUV that I ordered, equipped the way I wanted it. John and the entire sales staff were great! I have purchased/leased 4 other vehicles from this dealership and have always been treated well. If you want to avoid all of the seemingly normal drama that goes along with walking into a dealership, you need to try this one - you'll be pleasantly surprised.
