Tustin Buick GMC review
Dealer add ons are extremely high, we were able to work
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.

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.
