New and used 2025 GMC Sierra 1500 SLT trucks for sale near San Juan Capistrano, CA

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

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.

I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

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!

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.

visited this Anaheim dealership twice over two weeks. First was just looking around, then I checked out another dealership in Orange but ended up rushing back here to lease a Ioniq 5 with all-wheel drive. Juan Zúñiga handled everything from the get-go, and there was no pressure whatsoever. I test drove 3 cars, hopped in and out of them loads, and nobody rushed me. When it came down to talking about prices and terms, there was no competition with other dealerships. Totally happy with it all! Thank you so much!!

Came in on a Saturday afternoon shopping for a used vehicles, Brian was my sales rep. He was very patient and knowledgeable gave me and my family a lot of options and gave us time to think and make a decision. They are fast with the process and great to work with. Thank you Brain and driveline team making this process easy and convenient.

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

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

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.

Good quick service getting my new towing mirrors installed. Also cleared the check engine light. Steve Pacheco did a great job making the repair happen.
