New and used 2025 GMC Yukon for sale near Covina, CA

Tom & Jerry in real life way better than the cartoon. Got me exactly what I wanted in a reasonable amount of time.

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

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

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 first interaction with a representative from STG via cel phone did not result in a transaction that met my satisfaction. Some days later I was contacted by a different representative and things went very smoothly. Caesar Q and I reached an agreement that he confirmed by email. I drove down from San Jose with my trade in vehicle and a cashiers check and arrived well after dark. The truck was prepared and ready for me to perform a thorough inspection and test drive. I was inside, outside and under the truck and it was very clean and looked as good as it did in the photos. Caesar was a pleasure to meet and work with. Very friendly and easy to communicate with, he and I shared some similar interests. The paperwork went smoothly and Caesar explained everything about the process as we went along. I would not hesitate to shop at STG in the future even though it is a 7-1/2 hour drive for me. Thank you to Caesar Q and STG for making my truck buying experience a pleasurable one. Respectfully Thomas O.

Fantastic dealership with professional and courteous staff.
